Description

Since its introduction in 2014, the Star Adventurer has been at the forefront of the lightweight, portable astroimaging revolution. And now, with the Star Adventurer GTi, we take the next step with full GoTo performance in a compact package. The all-new Star Adventurer GTi features a built-in illuminated polar scope for precision alignment in EQ mode, ports for USB, autoguider, V-style dovetail, optional SynScan hand controller, and SNAP shutter control for your DSLR (programmable via Sky-Watcher’s free SynScan Pro app for iOS and Android). Star Adventurer GTi also includes a dual-position counterweight for use at low latitudes as well as full smartphone control via Wi-Fi. With the added GoTo feature plus multiple tracking rates including lunar, solar, and sidereal, the heavens are yours to capture and explore. With its 11-pound payload capacity, Star Adventurer is well-equipped to handle your DLSR or mirrorless camera sporting a wide-angle or telephoto lens plus accessories, a small aperture astrograph with a dedicated astro camera, or even small OTA’s such as our Skymax series of Maksutov-Cassegrain telescopes perfect for deep space objects, the Moon, and planets. Available in two configurations (with or without tripod and pier extension), Star Adventurer GTi is the perfect mount for the astrophotographer that wants the ultimate in both performance and portability.

    • Great little mount
Works well, though the SynScan app can be problematic upon occasion. When it is working, my goto’s were very good. I do astrophotography and use this with a guide scope/camera, through EQMOD and that works well. Some nights my total error is about 1.2-1.7 which isn’t great if you have a camera with very small pixel pitch. For mine not an issue. Other nights I can get about 0.6-0.8 total error. Goto’s with Stellarium and EQMOD work very nicely. And with no guide, good polar alignment I could get up to 2 min subs with a 200mm lens. ... show more

I have been using the SA GTi for about a month now and have been very satisfied. Its go to capability is a huge advantage over the SA 2i, since it saves time when locating the astronomical objects that you want to photograph or observe, but it also feels more robust, the knobs for polar alignment are better and allow adjustment easier and more precise. It is very easy to install and connect. The tracking is very precise and using guidance, I have been able to take 3 minute exposures with a 560mm telescope with an average error of less than 1 arc second. ... show more

    • Wow tracks like a more expensive mount.
I set this up with a Redcat51, a ZWO asi294 pro, asi120 guide camera controlled with an ASIAir. The first night I did the polar alignment using the ASIAir then slewed it to the North America nebula where I did my final focusing and did a few test images of about 1 minute each to make sure I had it framed how I wanted it. Well I set up a run of 10 pictures 3 minutes each but guiding failed during the first image, I didn’t set it up correctly so I just let it take the images anyway. Well I thought I was taking 3 minute integrations but I had checked 300 seconds and that is 5 minute integrations not 3 like I thought I was taking. To my surprise the images came out perfect totally round stars no trailing with no guiding. This mound tracks like a dream better than my LX200 but then again it’s had a much smaller focal length. The next day I setup again and 5 minute tracking was spot on both guiding and not guiding. I slewed to several targets that night and it hits its target almost dead on every time. This will be my camping setup nice and compact. ... show more

    • Great starter EQ drive for light gear
When I shot the recent Comet Tsuchinshan-ATLAS with my Fujifilm X-H1 on a geared-head tripod, using 0.5 second exposure, background star motion was visible in closeup. Later, I calculated that the stars had moved 6 pixels during that 0.5 second. The photos were still great, but this experience got me excited about an EQ clock drive. Research led me to this SA GTi -- good specifications, good reviews, and still relatively affordable. The 11-pound weight limit is the primary characteristic of the GTi. This is fine for modern cameras and "astrographs", small refractors designed 100% for astrophotography. I will update the review as I gain experience and results with the mount. The reason for only four-stars in my rating is that the polarscope LED is nonfunctional in the GTi that I received. I tried all the posted workarounds and even the alternate Windows package GS Server but no luck. I decided not to return the GTi but might at a later date seek a warranty repair. The reason is that traditional precise polar alignment is not that important for a "Go To" mount like this. Instead, after a basic polar alignment, two- or three-star alignment and synchronization are used to calibrate the internal computer for precise pointing and tracking. ... show more

    • Buyer beware: Bought "Like New". Came heavily used.
This purchase was a huge bummer. I bought this in hopes of taking to a star party as my first astro trip. It was listed as "like new open box" via Amazon. When it arrived everything looked okay until I looked a bit more closely: 1) The polar scope eyepiece was extremely loose and wiggly. 2) The polar scope illuminator would not light 3) The housing had defects including missing paint 4) The dovetail mount was out of alignment with the polar scope. Since I don't really know anything about astro yet, I opted to reach out to Sky Watcher for support. They told me none of those things were normal and to return the item to Amazon. So back it goes. Hopefully I will still be able to get some decent wide photos at the star party. Other than the defects, the unit did connect to the app and move, but without being able to polar align, the accuracy and function was severely affected. I will likely buy this unit from an approved dealer. Honestly, the open box discount wasn't even big enough to justify the headache. ... show more

    • Good
I liked the star tracker just what I needed. It’s a bit hard to setup but once you get used to it you can point at space objects. I had trouble trying to make it point at the objects correctly but with good alignment it works.

    • I got the used but in excellent condition model
I bought the used but in excellent condition model. There were some corroded batteries at one point in one of the battery carts and the corrosion extends to the contacts of the unit. The unit would not turn on with fresh batteries. I sent it back waiting for a refund.
