Sky-Watcher Sky-Watcher AZ-GTI – Portable Computerized GoTo Alt-Az Mount for On-The-Go Astronomy – WiFi Enabled App Controlled – Time-Lapse and Panorama Photography Capable (S21110)

entrega rápida, es resistente , el motor funciona bien. No me gusta la forma en que se asegura el tubo de telescopio a la montura pero es cuestión de apretar un poco la rosca, aunque no me da tranquilidad si se desgasta el mecanismo para asegurar el tubo, procuro apretarlo lo suficiente para no desgastar la placa de cola de milano y el tornillo

This mount as accompanied my 90mm achromat (my 6” newt also performed well on it) on virtually every trip I’ve taken, its ease of use is unparalleled at this price point. Once you’ve done a proper alignment, the go to system works without issue. The tripod is strong and stable yet lightweight. My only complaint is the design of the battery compartment. I wish the plastic material was a little more resistant as I feel a drop could break it and render it unusable

I picked this up as a light go-to mount to track space objects, for nights when I don't want to drag out the other heavy equipment I have. Most times, I put it out with a small telescope on it, use the phone app, align to three stars, and tell it what object I want to look at for the night. With it being battery powered and on my wifi, I can go from wanting to look at planets or deep space objects to having it set up and able to find anything in less than five minutes.If you want to use it for EAA (electronically assisted astronomy), you can use it as is because the rotation doesn't matter with the shorter exposures and the live stacking adjusts well. If you want to use it for full on astrophotography, you can easily get a wedge and polar align it like the other mounts and it works just as well. Out of the box, the tracking is pretty accurate, but if you want it even tighter, it does work with PHD.The only downside at all is that it doesn't have much of a max load, but that's to be expected with a small go-to mount. I have been able to successfully track on a wedge, holding my mirrorless with a 135mm lens and the stars all come out round without any streaks. Another thing that isn't a big deal but needs to be noted: if you get the eq wedge for this, there isn't an easy way to mount a polar scope to it so getting it polar aligned is a little trickier than for other mounts.This is great for users who want a more accurate goto mount for visual astronomy than the ones that come with the cheaper telescopes or more experienced astronomy/astrophotography users who just want something lighter to travel with or need to set up quickly. Battery life is great, along with connections with phones/tablets and the wifi.

Doesn't track very well even using a polar scope and 2 star alignment. The Star Adventurer 2i I had before and costs less tracked much, much better than this mount in EQ mode. I wish I had not purchased this model.

This mount has exceeded my expectations, as it is both more accurate in finding objects and more stable than I expected. I use it as part of my visual use “grab and go” system, which uses a Celestron 102AZ, 102mm, F6.6 refractor. It is far more stable with that telescope than the Twilight 1 manual alt-az mount that I was as using( and it is also somewhat lighter) and also much more stable than the manual alt-az mount that came with my 2016 purchase of this refractor. I use 3 star alignment with the Syscan app on my phone , and I am consistently well within the inner half of my field vision with a 25mm (26x) eyepiece. My whole setup, with the mount, refractor, 6x30 finderscope, and laser pointer only weighs about 16 pounds, so it is an easy carry. For the money this mount is a great value.

For its size and weight, this mount does a very good job with my 127 Maksutov, which is at the upper end of its weight-bearing capacity. I find the tracking to be a big help visually. For photography, you would want to do a very careful alignment and keep exposures short, because I doubt it's smooth and accurate enough for serious work. You cannot leave the mount tracking for long periods and expect an object to stay centered, but it usually gets within 1° when finding targets. There are clicking noises in certain orientations that probably mean there's some internal slop in the gearing, but overall I don't find the noise from mine objectionable. High-speed slewing is naturally noisier than fine adjustment.The iOS application works, but has a few limitations. It insists on remembering the previous alignment, even when you are trying to set a new one, which sometimes requires the "reset alignment" utility function and quitting the app. I had to update the mount firmware immediately, in order to fix bugs, but also to mount my scope on the right side (it defaults to the left). Skywatcher support was helpful in finding the right version. I have not had disconnection problems since the update. I think a mobile app has some advantages over a hand controller when searching for objects by their common name, providing information, and for portability.You'll want a battery that can keep your phone or tablet display on continuously, because constantly unlocking your phone to make an adjustment or pick a new target gets annoying. (You may want to purchase a power bank and/or AC adapter in preference to the internal AA batteries, which can also recharge your phone/tablet.)Now that there's an equatorial mode in the app, it would be nice if there were a matching EQ wedge/base, but most people seem to use the Star Adventurer Latitude base. I've heard of people using this mount with a C6 tube, but I think that's overloading it. It's ideal for a 72–90mm short-tube refractor, or the 100 and 127mm Maksutovs. I think some very light 102mm refractors and the C5 will work, too. I'm curious about adding a counterweight shaft (which is needed for EQ mode) since it's not clear what the weight limits are with one attached. I will probably also add a camera adapter to try some wide-field astrophotography.Overall, it's easy to recommend this mount at it's normal price (below 400) so long as you are patient with the app and aren't expecting it to replace a german equatorial or massive fork mount. I think it hits a sweet spot for amateurs who want more than a toy while keeping their investment modest, and portable enough to take along without thinking twice.
