Excelente Star Tracker
Revisão de T. F. em 03.05.2023 23:59:36( 5 / 5 )
Não sendo um profissional nesta matéria, recomenndo vivamente este Star Tracker, extremamente fácil de utilizar e a função GoTo é excelente. Equipamento bastante portátil podendo ser transportado em viagem. Este equipamento torna muito mais fácil a pesquisa de motivos em céu profundo. Tal como disse anteriormente, apesar do valor do investimento, recomendo para quem se está a iniciar neste hobbie!
A good mount - provided you know what to expect

This mount is a good mount marred by some baffling bad design decisions. It is well adequate for visual observation and tracking with a camera, provided you do not go into medium or high focal lengths. But I would not recommend it for astrophotography even with scopes as small as 60mm or 400mm focal length. To get it to work properly with those systems - well within weight restrictions - often requires the user to fiddle with the mechanics.
I bought this mount with the SW Evolux 62ED set and have never been able to go above 30s unguided - even then trails start to appear. The mount is extremely moody when tracking even with an guiding scope and camera. Not only that, but the internal workings could do with some improvement: from the start my Star adventurer GTi has had a large DEC backlash, in the range of 3-4 seconds (large, but the norm for this mount, judging by other users' experiences). But since I bought it, in the Summer, and with each subsequent use, that backlash has steadily gotten worse to the point where it is now over 5 seconds. This might be fine for visual observing but, especially in a mount/tracker advertised as a photographic one, is completely unacceptable. These problems would easily be improved upon by the inclusion of a spring that kept the screw controlling the gear tightening in place, for example, and there really isn't an excuse for Skywatcher not doing that aside from greed and unwillingness to provide an improvement that wouldn't be that expensive in the first place. Similar problems that I haven't personally encountered (yet) can be found all over internet forums. "You get what you pay for" doesn't really cut it here.
So yes, a good mount and very portable. Just be sure you know what you are getting to. Personally I would consider saving up for a better mount, and more future proof one. But if all you need is a tracker with no intention of upgrading your rig later down the line, this is a good choice.
