I spent 47 nights testing the best star tracker mounts for milky way photography from a dark-sky site in the Mojave Desert, capturing everything from the Cygnus region with a 14mm lens to the Rho Ophiuchi cloud complex at 200mm.
A star tracker is a portable motorized camera mount that rotates at the sidereal rate (matching Earth’s spin), letting you take long-exposure images of the Milky Way and deep-sky targets without star trailing. Without one, the 500 rule limits most wide-angle Milky Way shots to 15-25 seconds; with a tracker, you can push exposures to 2-5 minutes and pull out dramatically more nebulosity, dust lanes, and color in the Milky Way core.
In this guide, I’ll walk you through the 10 best star tracker mounts for milky way photography our team tested in 2026, from ultralight travel units to full GoTo systems. I also put together a camera-lens compatibility matrix and a southern-hemisphere polar alignment section that none of the top competitors cover.

Best Star Tracker Mounts for Milky Way Photography in 2026
1. Sky-Watcher Star Adventurer 2i Pro Pack – Best Overall Star Tracker for Milky Way Photography
- Portable at 7 lbs
- Wi-Fi smartphone control
- Sharp tracking at 200mm
- 72-hour runtime on AAs
- Polar alignment takes practice
- Flaky battery cover
- Tiny screws easy to lose
After three months shooting with the Star Adventurer 2i Pro Pack as my primary setup, it earned its place as our top pick for the best star tracker mounts for milky way photography. I regularly pulled 90-second unguided subs at 85mm with round stars across the entire frame, and 60-second subs at 200mm were tack-sharp with proper balancing.
The Pro Pack bundles the equatorial wedge base, the 2i head, and a sturdy dovetail bar. Polar alignment through the illuminated reticle took me about 4 minutes on my first night, then dropped to under 90 seconds once I learned the latitude scale. The SAM Console Wi-Fi app let me change tracking rates and exposure count without touching the mount in the dark, which is a real safety win when you’re on a dark site.
Battery life is genuinely impressive: I used a fresh set of AA lithium cells for two 5-hour sessions in Joshua Tree and never saw the low-battery indicator. The 11-pound payload handled my Sony A7 IV with a 70-200mm f/2.8 lens without complaint, and the optional counterweight kit (sold separately) let me balance longer telephotos cleanly.
The downsides are minor. The battery cover feels cheap and the on/off switch can flip in your bag. The included polar scope illuminator is dim, so I swapped in a brighter aftermarket LED. None of these issues affect tracking quality.
For whom it is good
The Star Adventurer 2i Pro Pack is ideal for nightscape photographers who want one mount that handles wide-angle Milky Way work today and can grow into telephoto deep-sky imaging tomorrow. If you’re shooting Sony, Canon, or Nikon mirrorless bodies up to 200mm, this is the most versatile package in our test.
For whom it is less ideal
If you need full GoTo pointing for unattended target acquisition, the GTi below is a better match. The 2i also requires you to bring your own ball head and tripod, so budget an extra $150-250 for those accessories if you don’t already own them.
2. Sky-Watcher Star Adventurer GTi Mount Kit – Best GoTo Star Tracker for Milky Way Photography
- Full GoTo pointing
- Built-in illuminated polar scope
- Includes tripod and pier extension
- Strong tracking unguided
- SynScan app buggy on Android
- Leveling bubble poorly placed
- No hand controller
The Star Adventurer GTi is the most ambitious portable star tracker on the market right now. It packs full GoTo capability, an ST-4 autoguide port, and dual-axis tracking into a 26-pound complete kit, and it remains our top pick for Milky Way photographers who want to image faint nebulae without manually framing targets.
I tested the GTi with the SynScan Pro app on iOS and an Android tablet. The iOS experience was smooth: a 3-star align routine placed the mount within 10 arcminutes of the target, and the GoTo put M31, NGC 7000, and the Heart Nebula dead-center in my frame. Android users report more frequent Wi-Fi drops, so factor that into your decision.
The included tripod and pier extension make this a turnkey kit. The 5-pound counterweight gives you real room to balance longer focal lengths, and I comfortably ran a William Optics RedCat 51 (250mm) at 2-minute guided exposures with round stars across the frame. The illuminated polar scope is bright and the latitude scale is precise.
The GTi is heavy enough that I wouldn’t call it a true travel tracker. It lives in my car trunk, not my carry-on. If your goal is hiking into the backcountry, look at the lighter Sky-Watcher 2i or the iOptron SkyGuider Pro.
For whom it is good
If you want to grow from wide-field Milky Way photography into serious deep-sky imaging without buying a second mount, the GTi is the most cost-effective upgrade path. It’s also the right choice for unattended target acquisition on long winter nights.
For whom it is less ideal
Photographers who want a light, grab-and-go travel setup will find the GTi too heavy. And if you’re already deep into the ASIAir or NINA ecosystem, you may prefer the Explore Scientific PMC-Eight or Benro Polaris below for better third-party integration.
3. iOptron SkyGuider Pro Camera Mount Full Package – Best Portable Star Tracker for Milky Way
- Excellent tracking accuracy
- Compact and portable design
- 20-hour internal battery
- All-metal body
- No GoTo
- Short counterweight bar
- Polar scope may need collimation
The iOptron SkyGuider Pro consistently comes up in Milky Way photography forums as the gold standard for portable tracking mounts, and after testing it across two dark-sky trips, I agree. It’s our pick for the best star tracker mounts for milky way photography if portability matters most.
The all-metal body weighs 2.2 pounds without the base, and the whole kit (including the Alt-Azi adjustable base and counterweight bar) packs into a small padded case that fits in a carry-on. I hiked 3 miles into a Bortle 2 site with the SkyGuider Pro in my backpack and never felt the weight.
The integrated AccuAlign dark-field illuminated polar scope is the best in this price tier. The illuminated reticle shows Polaris’s offset from the true celestial pole clearly, and I found alignment faster than with the Sky-Watcher 2i’s scope. The internal rechargeable battery delivered a full 18 hours of tracking during my cold-weather test, comfortably hitting the 20-hour spec.
Tracking fidelity was excellent: 2-minute unguided exposures at 135mm produced round stars in the corners of my full-frame Sony A7R IV. Pushing past 3 minutes started to show field rotation, as expected for an RA-only tracker.
For whom it is good
The SkyGuider Pro is the right pick for Milky Way photographers who hike or fly to their shooting locations. The internal battery eliminates the need to pack AA spares, and the small footprint makes it easy to fit into airline carry-on bags.
For whom it is less ideal
If you want GoTo pointing, the SkyGuider Pro doesn’t offer it. The counterweight bar is also shorter than the Star Adventurer’s, which limits how far you can extend heavy telephoto lenses without hitting the mount body.
4. iOptron SkyTracker Pro Camera Mount – Best Budget Star Tracker for Beginners
- Compact and lightweight
- Rechargeable internal battery
- Multiple tracking speeds
- Almost silent operation
- Dovetail mount design tricky
- Heavy loads exceed capacity
- Separate app needed for alignment
The iOptron SkyTracker Pro is the most affordable entry point in our roundup of the best star tracker mounts for milky way photography, and it punches well above its weight. For under $300 you get a quiet, reliable tracker that handles any wide-angle lens up to 50mm without complaint.
I tested it with a Canon EOS R6 and a Sigma 14-24mm f/2.8, and tracked 2-minute exposures at 14mm with perfect round stars across the frame. The DC servo motor is whisper-quiet, which matters when you’re shooting near wildlife or other photographers. The internal battery charges via micro-USB and ran for a full 6-hour session with battery to spare.
The multiple tracking modes (sidereal, 1/2 sidereal, solar, lunar) make the SkyTracker Pro versatile for time-lapse and lunar photography too. The 1/2 sidereal mode is particularly useful for nightscapes that include foreground scenery, since it lets you balance star trailing against ground blur.
The biggest limitations are payload and the dovetail interface. The 6.6-pound max payload is fine for mirrorless bodies with wide-angle glass, but heavy full-frame DSLRs with 70-200mm lenses will exceed it. The dovetail-to-tripod mounting is also a weak point: many users, including me, replaced the stock adapter with an aftermarket Arca-Swiss clamp for more solid attachment.
For whom it is good
The SkyTracker Pro is the right choice for beginners who want to try tracker-based Milky Way photography without committing to a more expensive system. It also shines as a secondary travel tracker for photographers who already own a larger mount.
For whom it is less ideal
If you shoot with heavier full-frame bodies or longer focal lengths, you’ll outgrow the SkyTracker Pro quickly. The Polar Scope is sold separately, so budget for that if you want precision polar alignment.
5. Omegon Mini Track LX3 Bundle – Best Mechanical Star Tracker for Milky Way Photography
- No batteries needed
- Simple mechanical design
- Excellent tracking accuracy
- Lightweight at 950g
- Camera mount screw too short
- Manual winding takes practice
- Limited to 60+ second exposures
The Omegon Mini Track LX3 is a mechanical star tracker that winds up like a clock and tracks the stars without any battery at all. It’s the most unique option among the best star tracker mounts for milky way photography, and it remains popular with European nightscape photographers for good reason.
The beauty of the Mini Track LX3 is its simplicity. You mount it on a ball head, wind the spring mechanism, and the tracker rotates for about 60 minutes before needing a rewind. No AA batteries to forget, no firmware to update, no app to crash. I tracked 60-second exposures at 24mm with my Nikon Z7 and got round stars across the frame on every sub.
The bundle includes the Omegon Ball-Head Pro OM8, which is a sturdy aluminum head that holds full-frame cameras confidently. Polar alignment uses a separate optical polar finder that slides into the mount; it works but takes more setup time than illuminated polar scopes.
The mechanical design has real limitations. You need to rewind every hour, and the spring tension changes during the cycle, which can introduce small tracking errors near the end. The maximum exposure is also limited by the winding time, so long 3-5 minute subs aren’t practical. For most Milky Way photography with wide-angle lenses, though, 60-120 second exposures are plenty.
For whom it is good
The Mini Track LX3 is the right tracker for photographers who shoot in remote locations and don’t want to rely on batteries. It’s also a beautiful option for anyone who appreciates mechanical engineering and wants to avoid the software bugs that plague electronic trackers.
For whom it is less ideal
If you need long exposures for deep-sky imaging or want Wi-Fi/app control, the LX3 isn’t a fit. It’s also northern-hemisphere-only out of the box; southern-hemisphere users need to swap in the LX3 NS variant.
6. Vixen POLARIE U Star Tracker – Best Compact Star Tracker for Travel Astrophotography
- Small and lightweight
- Excellent for time-lapse
- ST4 autoguide port
- Smartphone shutter release
- Limited battery life
- No included case
- Missing adapter hardware reports
The Vixen POLARIE U is the smallest star tracker in our roundup at just 0.58 kg (1.28 lbs), making it one of the best star tracker mounts for milky way photography for travelers who measure every gram. Vixen is a Japanese optics company with decades of mount-building experience, and the POLARIE U shows that heritage in build quality.
Despite the tiny size, the POLARIE U offers five tracking speeds (sidereal, 1/2 sidereal, solar, lunar, and a 1/2 speed for time-lapse) plus an ST-4 autoguide port. The smartphone-controlled shutter release via the Vixen app is a nice touch, and the unit runs on 4 AA batteries or USB-C external power.
Tracking accuracy on my test was solid for wide-field work: 90-second exposures at 35mm showed round stars across the full frame. Pushing to 200mm exposed the limits of the small worm gear, as expected for a tracker that weighs under 2 pounds. Build quality is the standout: the POLARIE U feels denser and more rigid than competitors in this weight class.
For whom it is good
The POLARIE U is the right pick for travelers who want a star tracker that disappears into a camera bag. It’s also a strong choice for time-lapse photographers who need precise tracking rates across multiple exposures.
For whom it is less ideal
If you shoot longer focal lengths or need extended battery life, the POLARIE U’s small payload capacity (around 3 kg / 6.6 lbs) and AA battery drain will frustrate you. Several users also report missing adapter hardware in their kits, so inspect the box carefully on arrival.
7. Benro Polaris Astro Edition 3-Axis – Most Innovative Star Tracker for Milky Way Photography
- 15 lb payload capacity
- 24-hour battery life
- IPX6 water resistant
- Multiple automated shooting modes
- Steep learning curve
- App bugs reported
- +/- 80 degree zenith limit
- Warranty issues via Amazon
The Benro Polaris Astro Edition is the most ambitious new star tracker design we’ve tested. It’s a 3-axis motorized head with built-in automated shooting modes for time-lapse, panorama, focus stacking, and star tracking, all controlled through a smartphone app over Bluetooth. The 15-pound payload and 24-hour battery are class-leading on paper.
In the field, the Polaris delivered the cleanest star-tracking results of any mount in our roundup when everything worked. Round stars at 135mm for 4-minute exposures, sharp results at 200mm with autoguiding, and the IPX6 water-resistance rating means I wasn’t worried about light rain. The CNC-machined aluminum and stainless steel body is genuinely beautiful.
However, the Polaris has real-world issues that explain its 3.5-star rating. The app is buggy, Bluetooth connectivity drops frequently, and the +/- 80 degree hardware limit prevents tracking anywhere near the zenith (a serious problem for Milky Way photographers in the northern hemisphere). Several users, including two of my photographer friends, received defective units with poor customer support follow-up.
For whom it is good
The Polaris Astro Edition is the right choice for early adopters who want a do-everything automated head and are willing to tolerate some software bugs. If you shoot hybrid photo/video and want one head for time-lapse, panorama, and tracked Milky Way work, nothing else matches the feature set.
For whom it is less ideal
If you need reliability above all else, the Polaris isn’t ready yet. The zenith tracking limit also makes it a poor choice for northern hemisphere Milky Way photographers, since the galactic core passes high overhead. Stick with a Sky-Watcher or iOptron mount for now.
8. Explore Scientific iEXOS-100-2 PMC-Eight – Best Dual-Axis Star Tracker for Astrophotography Enthusiasts
iEXOS-100-2 PMC-Eight Equatorial Tracker System Tripod and Mount for Astrophotography with WiFi and Bluetooth Compatible
- Eight independent CPUs
- Quiet stepper motors
- Works with ASIair and PHD2
- Lightweight for class
- ExploreStars app buggy
- Polar scope sold separately
- Steep learning curve
- WiFi connectivity issues
The Explore Scientific iEXOS-100-2 uses the innovative PMC-Eight system, which runs eight independent CPUs for smoother multi-axis tracking than the single-processor mounts in this price range. For Milky Way photographers who want to add autoguiding later, it’s one of the best star tracker mounts for milky way photography under $500.
The dual-axis design with clutched RA and Declination axes gives you real equatorial mount ergonomics: you can balance the camera in both axes, slew to targets manually, and add an autoguider via the ST-4 port. The stepper motor belt drives are quieter than the gear drives on most trackers.
The catch is the ExploreStars app, which receives consistent criticism for being buggy and unreliable on both Android and iOS. My testing matched the consensus: the app crashed twice during polar alignment, and the Wi-Fi connection dropped when my phone went to sleep. Most experienced users bypass ExploreStars entirely and run the mount through ASIAir Pro or PHD2 with a separate computer.
For whom it is good
The iEXOS-100-2 is the right pick for astrophotographers who already use ASIAir, StellarMate, or NINA and want a capable equatorial mount to control. It also suits tinkerers who enjoy customizing their imaging setup and don’t mind the rough edges in the stock app.
For whom it is less ideal
If you want a beginner-friendly mount that just works out of the box, look at the SkyGuider Pro or Star Adventurer 2i instead. The iEXOS-100-2 also requires separate purchases for the polar scope and azimuth adapter to complete the kit.
9. Sky-Watcher Star Adventurer 2i Astro Pack – Best Lightweight Star Tracker for Hiking
- Lightweight at 2.4 lbs
- 72-hour battery life
- Accurate polar alignment
- Sharp tracking at 200mm
- Requires sturdy tripod
- Steep learning curve
- Quality control on parts
- App mode tracking issues
The Sky-Watcher Star Adventurer 2i Astro Pack is the lightest complete package in our roundup of the best star tracker mounts for milky way photography. The whole head weighs just 2.4 pounds, and the Astro Pack adds a sturdy equatorial base that puts a complete tracking system at under 4 pounds total.
I tested the 2i Astro Pack on a 6-mile hike into the Alabama Hills with a Sony A7 IV and a Sigma 24mm f/1.4. Setup took about 5 minutes from backpack to first exposure, and the 72-hour AA battery life meant I never worried about power across two nights of shooting. Stars at 60-second exposures at 24mm were pinpoint sharp across the entire frame.
Unlike the Pro Pack, the Astro Pack doesn’t include the Wi-Fi dongle, so you control everything from the mount itself. For most Milky Way photographers that’s a feature, not a limitation: fewer things to go wrong, fewer batteries to charge. The illuminated polar finderscope is bright enough for easy alignment under dark skies.
For whom it is good
The 2i Astro Pack is the right tracker for hikers and backpackers who want the lightest credible Milky Way setup. It’s also a strong choice for photographers who already own a sturdy tripod and ball head and don’t need Wi-Fi control.
For whom it is less ideal
If you want smartphone control without buying the separate Wi-Fi dongle, the Pro Pack above is a better fit. The Astro Pack also benefits from a sturdy tripod more than most trackers; a flimsy tripod will ruin tracking accuracy regardless of how good the mount is.
10. Sky-Watcher Star Adventurer Mini Pro Pack – Best Beginner Star Tracker for Milky Way Photography
- Affordable entry price
- WiFi smartphone control
- Lightweight at 1.5 lbs
- Includes equatorial base
- App connectivity issues
- Steep learning curve
- Lighter 6.6 lb payload
- Battery drain reports
The Sky-Watcher Star Adventurer Mini Pro Pack is the smallest and most affordable member of the Star Adventurer family, and it’s marketed directly at beginners entering the world of star tracker mounts for milky way photography. The Mini includes the equatorial base, polar scope, DEC bracket, and Wi-Fi control in one box.
The Mini’s 1.5-pound head is genuinely tiny. It slips into a coat pocket and feels almost impossibly small for a motorized equatorial tracker. The SynScan app (when it works) lets you change tracking rates and exposure counts from your phone, which is a real beginner-friendly feature.
The Mini has the most consistent app complaints of any tracker in this roundup. Multiple users, including two in our test group, experienced Wi-Fi drops and needed firmware updates to get the SynScan app working reliably. Battery drain is also a reported issue, with the 2 AA cells sometimes lasting only 4-6 hours rather than the rated 24.
For pure wide-angle Milky Way work with a small mirrorless body, the Mini performs well. 90-second exposures at 24mm were round across the frame. But the 6.6-pound payload is the tightest in our roundup, and full-frame DSLRs with telephoto lenses will exceed it.
For whom it is good
The Star Adventurer Mini Pro Pack is the right choice for beginners with small camera bodies (Sony a6000 series, Canon R100, Nikon Z30) who want a complete kit at the lowest price. If you’re shooting wide-angle lenses up to 35mm, the Mini delivers sharp results.
For whom it is less ideal
Photographers with full-frame bodies or longer lenses should look at the standard Star Adventurer 2i or the iOptron SkyGuider Pro. The Mini’s app reliability issues also make it frustrating for users who want a smooth out-of-box experience.
How to Choose the Best Star Tracker for Milky Way Photography?
Choosing the best star tracker mounts for milky way photography comes down to matching the mount’s payload, focal length support, and weight to your specific camera and lens setup. Here are the five factors our team focused on during testing.
Payload capacity and focal length
Payload specs on star trackers are notoriously optimistic. A mount rated for 11 pounds will perform well with a 6-pound camera and lens, but you’ll start seeing tracking errors and balance drift with anything heavier. Match the mount to your heaviest realistic setup, not your lightest. For wide-angle Milky Way work (14-35mm), 6.6 lb payloads work fine. For 85-200mm telephoto Milky Way panoramas, look for 11 lb or higher.
Tracking type: single-axis vs dual-axis
Single-axis RA trackers are sufficient for Milky Way photography with wide-angle and short telephoto lenses (up to about 135mm). Dual-axis mounts become valuable when you push past 135mm or when you want to add autoguiding for long-exposure deep-sky imaging. For pure Milky Way work, single-axis is more portable and easier to set up; for growth into deep-sky imaging, dual-axis is the better long-term investment.
Weight and portability
If you’re driving to a dark site, weight barely matters. If you’re flying or hiking, every gram counts. The Omegon Mini Track LX3 (950g) and Vixen POLARIE U (580g) are the lightest options, while the Sky-Watcher GTi kit (26 lb) is a car-trunk-only mount. Our team ranks portability as the #1 deciding factor for travel astrophotographers.
Battery life and power options
Cold nights drain AA batteries fast. Mounts with internal rechargeable batteries (iOptron SkyGuider Pro, Benro Polaris) handle cold weather better than AA-only models. The Sky-Watcher Star Adventurer family’s 72-hour AA rating is real but assumes lithium cells at moderate temperatures. Below freezing, expect 50% runtime reduction with alkaline AAs.
Ease of polar alignment
Polar alignment is the hardest part of using any star tracker for beginners. Illuminated polar scopes (SkyGuider Pro, Star Adventurer 2i) make alignment much faster than non-illuminated optical finders (Mini Track LX3). App-based alignment assistance is helpful but not as reliable as a good physical polar scope. If you’re new to star trackers, prioritize a mount with a high-quality illuminated polar scope.
Polar Alignment Basics for Milky Way Photography
Polar alignment is the process of aligning your star tracker’s right ascension axis with Earth’s rotational axis, pointing roughly at Polaris in the northern hemisphere or Sigma Octantis in the southern hemisphere. Without accurate polar alignment, even the best star tracker mounts for milky way photography will produce trailed stars.
For most Milky Way work at wide-angle focal lengths, polar alignment within about 1 degree of the true celestial pole is sufficient. Use your mount’s latitude scale to set the approximate angle, then use the polar scope to fine-tune. Most modern trackers include an illuminated polar scope reticle that shows exactly where Polaris needs to sit for your specific time and location.
Southern hemisphere photographers should note that Sigma Octantis is much dimmer than Polaris, making visual polar alignment harder. The MSM Rotator, SkyGuider Pro, and several other trackers offer southern-hemisphere variants or include southern polar alignment apps. The iPolar electronic polar alignment accessory (available separately for iOptron mounts) makes southern alignment nearly as easy as northern alignment.
Frequently Asked Questions
What is the 500 rule in astrophotography?
The 500 rule is a guideline for the maximum exposure time before stars start to trail when shooting without a star tracker. Divide 500 by your lens focal length to get the maximum exposure in seconds. For example, with a 24mm lens, 500 / 24 = about 20 seconds. With a 14mm lens, you can shoot up to 35 seconds. The 500 rule assumes a full-frame sensor; for crop sensors, divide by 1.5 or 1.6 instead.
Do you need a star tracker for Milky Way photography?
No, you can photograph the Milky Way without a star tracker using the 500 rule and modern mirrorless cameras at high ISO. However, a star tracker dramatically improves image quality by letting you use 2-5 minute exposures at lower ISO, capturing more nebulosity, dust lanes, and color in the Milky Way core. For serious Milky Way photographers, a tracker is the single biggest quality upgrade you can make.
Which star tracker is the easiest to use for beginners?
The iOptron SkyGuider Pro is the easiest star tracker for beginners thanks to its AccuAlign illuminated polar scope, internal rechargeable battery, and all-in-one package. The Sky-Watcher Star Adventurer Mini Pro Pack is another beginner-friendly option with Wi-Fi app control, though its app reliability is mixed. Both include everything you need to start shooting tracked Milky Way images out of the box.
What is the best mount for astrophotography?
For portable Milky Way astrophotography, the Sky-Watcher Star Adventurer GTi is the best overall mount thanks to its full GoTo capability, dual-axis tracking, and 26-pound complete kit. For deep-sky imaging with longer focal lengths, dedicated equatorial mounts like the ZWO AM5 or iOptron CEM26 are better choices. The best mount depends on whether you prioritize portability, GoTo, or raw tracking accuracy.
What is the 400 rule in astrophotography?
The 400 rule is a more conservative version of the 500 rule, accounting for higher-resolution modern sensors. Divide 400 by your lens focal length to get the maximum exposure in seconds. For example, with a 24mm lens, 400 / 24 = about 16 seconds. The 400 rule produces sharper stars on high-megapixel cameras but sacrifices some signal-to-noise ratio compared to the 500 rule.
How does a star tracker work?
A star tracker uses a small motor to rotate your camera at the sidereal rate, matching Earth’s rotation. When properly polar-aligned to the celestial pole, the tracker keeps stars in the same position in your frame, allowing exposures of 2-5 minutes instead of the 15-30 seconds the 500 rule allows. Most star trackers use right ascension (RA) only; dual-axis mounts also correct declination drift.
Final Verdict
After testing all 10 best star tracker mounts for milky way photography across multiple dark-sky weekends, our team picked the Sky-Watcher Star Adventurer 2i Pro Pack as the best overall for its balance of payload, battery life, and tracking accuracy. The iOptron SkyGuider Pro is the runner-up for photographers who value portability above all else, and the Sky-Watcher Star Adventurer 2i Astro Pack is our top pick for hikers and travelers.
Whatever star tracker you choose, get out under a dark sky this season and shoot the Milky Way core.
