Sky-Watcher Star Adventurer 2i Pro Pack – Motorized DSLR Night Sky Tracker Equatorial Mount for Portable Nightscapes, Time-Lapse and Panoramas – Wi-Fi App Camera Control – Long Exposure (S20512)

I'm predicting my review of this Skywatcher camera equatorial mount, based on my several years of service as the Chairman of the Instrument Committee of an Ohio Astronomical Society. I maintained our many telescopes and helped many folks with their personal telescopes. I've built telescopes. I bought this little mount for my Sony a7rV camera and various lenses, the heaviest being the Tamron 150-500mm telephoto. First, and foremost, this mount is NOT meant for a telescope; it's meant for astrophotography with a camera. Many moons ago, the only way to take a decent photo of a deepsky faint fuzzy, was with a large computerized telescope and CCD camera. Way back in tbe days of the dinosaurs (back in the 80's - 90's) we still used old SLR cameras, lenses, and 35mm film. One photo took hours (I'm not exaggerating). Now phones do what couldn't be done back then. Telescopes and those CCD cameras cost several thousand dollars. My first CCD was a whopping 480 x 720 pixel. We've come a long way! Telescopee mounts should be very substantial, and capable of tracking for long periods. For a first telescope, I still recommend a reflector on a dobsonian base, preferably 6 or 8" primary mirror. The name of the game is to get much light to your eye as possible. Having said that, the camera works on accumulative light; that's why it'll pick up details that you'll never see. My interest is to be able to track for up to 30 minutes without having to make a correction. I'm sure this unit has that capability. For ANY mount to work properly, it absolutely MUST be balanced (not slightly balanced; not almost balanced). I had to buy a second weight for the mount to balance the Sony with the Tamron big boy with a total weight of 6 pounds. You have to be able to move your camera at any angle without the weight(s) or camera making a counter movements. When I balance my camera, I move it back and forth, correcting the weight as needed, until I get zero movement backlash; then I test it again. This way, you won't tear up the mount axis', and your tracking will be much more accurate. If you change your lens, you must repeat balancing. I've put the mount on an Innorel carbon fiber Tripod with a fluid pan head capable of pointing straight up or down (most pan heads won't go 90° straight up; the Innorel does. It pivots +/- 90°. Photo #3). I prefer pan heads over ball head mounts. But, either type will work, as long as they support the total weight of the mount, camera, lens, and any other accessories. I prefer components that will support 2-3x the weight. The Innorel GT344C mount won't flex even if I lean my 200 pounds on it; it has a load capacity of 25kg (55 lbs) The Innorel F20 fluid pan head, with its 90° movement, has an 11kg load capacity [23 pounds]; it easily handles the weight of my camera with the heaviest lens (96oz = 6lbs) + Skywatcher mount (4 pounds). The weights are for balancing, which when in balance, means zero wear on any mount. The Innorel mount and tripods are available here on Amazon. I've bought 2 of each, because I was so impressed with them. I keep the Skywatcher on one of them permanently. It's important to download the app on your Computer and/or phone, or at least, use an app to find the accurate position of polaris, based on time, date, and location. Polaris actually circles the north celestial pole. I've tested the app and it works perfectly on my Samsung phone and Windows 11 computer. Note that the app is not for slewing (moving the camera fast), but it will correct nicely. I connected the mount via wifi. Please take note that the Skywatcher creates its own wifi Hotspot. You connect directly to the mount, not through your network. Neither my phone or the computer had any problems with connection, and I tested the connection for 2 hours on each. It never dropped. The tracking capability and accuracy predicates on how well you polar align the mount. The more experience you have, the easier this will be. Please don't get discouraged; polar alignment may take you a couple of tries, but like many hobbies, you'll get used to it and it'll come automatically. There are good instructions, and YouTube videos on polar alignment, which would mean more to you than my instructions, so I encourage you to check them out. View several videos until you find one that clicks with you. To polar align this (or any mount) you need to be able to readily see through the the polar finder scope, and adjust the mount accordingly. That means getting that polar aligment scope high enough so you can easily see through it and make adjustments, without undo pain. I say that, because I'm a disabled veteran, and a plate in my neck, and apparatus in my spine, limit my movement. But, the Skywatcher makes polar alignment as easy as I've ever seen. Once you get going on your target, it'll track. It has an outlet for a autotracking, a nice plus. I bought the total package, including polar alignment base/scope for $359 here on Amazon. So with the cost of tripod/pan head, and Skywatcher, I've invested ~ $500-/550, which I consider to be a good investment for astrophotography. I've also tested it using a power supply that i bought here on Amazon, and it works perfectly. I'll submit photographic results of deepsky photos as the weather permits.

Hands down the best beginner piece of Astrophotography equipment. Ease of us for a total newb I would say is a 7 out of 10. No steep learning curve. Very well made and I know with Star Adventurer if I had a problem their customer service would be easy to get ahold of. This product hand down should be in every astrophotographers bag from beginner to seasoned pro due to it light and portability. The only thing i wish was that it had a better light for the polar alignment I wish it was built in like their GTI model

Used it to mount my Sony mirrorless camera for astrophotography. I have a large Celestron 8 inch (200m) computerized SCT scope but this one is so much easier to carry on trips ! Once properly polar-aligned it tracks extremely well. I did 50x10 sec and 50 x 20 sec exposures as tests (around here we have a bit of light pollution) and once stacked they came out amazing. The phone app works very well too. Five stars for quality, design and useability out of the box ! A couple of more specific comments : (1) carry four replacement AA rechargeable batteries for extended fun, or a usb cable (2) the red light plastic mount is a bit flimsy, I downloaded and printed a 3d file from thingiverse (3) A sturdy tripod is a must, (4) I prefer for my camera the more solid mount with the counterweight, this leaves the hole for the polar alignment unobstructed, that way you can always check later that all is still well, (5) you will definitely need a shutter release cable for your camera, mine is a short Vello cable from BH Photo; it will work with some normal remote shutter releases as well, so you can just use one cable. EDIT : After three evenings of observing and picture taking, the drive motor started to behave erratically. On power on ("star" mode) it would accelerate unpredictably, and then quit with the light blinking. A few fixes were suggested: * new fresh aa batteries, did nothing * factory reset, it did nothing. * back out that m3 set screw on the bottom, did nothing. It acts as some sort of gear tensioner. It had no loctite on it and was quite loose, so who knows where it's supposed to be ? All the way in minus a quarter turn? *updated the firmware to version 314, I don't think that did anything either. Plus it's unclear what version was in there before. As a last resort, I decided to open the case for some inspection. There's four M3 black screws that hold the metal lid. Once opened, there was nothing obvious to note, the gears looked clean, some clear grease, all the wiring seemed connected and in place. Surprisingly the unit would start running full speed when it was tilted around 45 degrees, then stopped when I rotated it back (flat on its back). Is there some sort of gravity sensor ? I decided to blow some compressed air (the aircan one) into the case, and that seemed to have stopped the erratic motion. Magic ? Maybe some dust or metal chips somewhere ? In the evening I took it out again, and it worked perfectly for three hours. Go figure. Any comments ? EDIT : On the second trip to the desert that tiny stainless steel threaded ring that hold in place the SNAP connector to the camera flew off never to be see again (see picture). I guess it had not been threaded in properly at the factory. So then the built in (app-based) intervalometer does not work any more. As a result I could not take pictures since I did not carry an extra cable intervalometer...

The sky watcher star adventurer pro is a good mid level star tracker. The device is well built and tracks well when properly aligned. The alignment, particularly for deep sky objects, can be a bit tedious but when done properly I have not had any noticeable movement using a 300 mm focal length and three minute exposures. It also performs well for general night sky photography and the alignment is much more forgiving. The battery life is good, I have shot about 40 hours on one set of AA batteries and have not had to replace them yet. I have not used the usb power source. The device has built in wi-fi (if it is the 2i) and an autoguider port. I have not used either to take photos though. The app that works with the device is somewhat lacking and basic. Hopefully it is updated soon. The kit is rather light, so it is easy to travel with. One of the drawbacks of this setup is the lighting of the polar scope. There is an external light and battery that must be connected into the front of the scope and turned on. The pieces are small and if you want to check the alignment after putting on the mount for the camera it won't quite fit. I usually just rig a red light from my head light instead of using the provided light. Overall it is a good mid-level mount. It is not for large telescopes or extreme focal lengths though.

If you are expecting Astrophysics quality this is not for you. But, for the price it cannot be beat. I bought the Pro pack so I could try different camera mounting configurations and see what works best. Unlike some other reviewers I had no quality control issues with the unit I received. The finder reticle alignment was spot on as received. You do need a very sturdy mount to properly support the tracker. My regular light weight camera tripod would not cut it. I needed a very sturdy tripod or I clamped the equatorial wedge to a picnic table. After some practice polar alignment was pretty straight forward. I did find it helpful to put a piece of tape on the meridian offset scale to keep it from moving around while setting the date and time. I do not usually use the supplied reticle illuminator because it will not fit with the camera in place. My red LED flashlight worked well however. Attached is a photo of the Andromeda Galaxies taken with a Canon T3i with the kit zoom lens at 250mm focal length. I found a waterproof plastic carrying case at Harbor Freight that fits the packing foam from the original box. Now everything is well protected and I can travel with the setup.

This is a sturdy sky tracker with good weight capacity, and also easy to operate. The shipping was also really fast.

OK, For many years I have wanted to take long exposures of the night sky. Finally, now that I'm several months away from retirement an I don't fish. I took the plunge to start my hobby. I researched telescopes that have go to mounts, mounts with out telescopes, and cameras. I settled on a T8i and the star Adventurer 2i. The star Adventure 2i seemed able to handle the camera equipment I wanted to use. And seemed a good starter unit. So if I decided not to continuethe hobby, not to much money out lay. Also, the unit could control my camera and also used to take panoramic photos, There is a steep learning curve to do polar alignment. DO NOT PUT POLARIS where the cross-hairs are do google YouTube on how to set up polar alignment with the star adventure 2i. Over all the unit is easy to set up, slaved to my computer using star adventure WiFi and off I went. I use the supplied dovetail for my camera. Star Adventurer 2i has 7 modes, The two modes that I currently use are Astrophotography mode and APP (star adventure mini console app mode). Now on to lost/misplaced parts One is the lens cap. no problem with that a old 35mm container works great. The other is the adapter to connect the polar illuminator to the dovetail. Still working with sky-watcher to replace the unit. Now on to would I buy the unit again knowing what I know now. Yes I would. Customer service? They will work with you. Though I must say they sent me a 1/4" lock washer for to replace the polar adapter. and you can not buy another one on their web site. I believe that the illuminator and other spare parts should be there so you could buy them. Nor can you buy the st-4 cable from them. If you lose or break a small part you can not replace it. That is reason I gave them a 3 and not a 5. An yes I do like the unit and I do have a work around for the adapter.

Very easy to use and well-made. There are few things that need to be improved. The battery cover is a little flimsy and the on/off mode switch is too easy to toggle while being transported, which can drain your batteries. Overall, I am mostly pleased with the design and very happy with the performance. So far I’ve only used the basic settings. I’m using a Canon 800d with a Rokinon 135mm. Polar alignment was very easy and my first time trying it out I was easily able to get 2” exposures with solid stars.

Excelente producto, y fácil de usar, quedé encantado con el resultado.

works fine

Last night, I visited the Razeen Desert in Abu Dhabi to capture the Milky Way, and the results were amazing. I exposed my camera shutter for 4 minutes and took multiple photos, resulting in detailed and noiseless images of the Milky Way. The main thing is to first align with the North Star, Polaris, as described, and then shoot.

A great add for my pass time

mine didn't work from the start.
