Hello There everyone. I'm thinking about purchase a telescope(I'm 100% new). I came over Astrobiscuit's youtube channel just randomly by a recommended video . one of his clips was where he and some other youtubers whos doing astrophotography, did a comparison on different scopes to use for different thing(best budget, best observer, best astrophotography and best allarounder), one of them was a budget scope(wich im looking for to start with) was Sky-watcher-80... My local store/webstore has different versions of the 80mm. so i wonder whats the actual differance between these 3? Sky-Watcher Startravel-80 EQ1 vs Sky-Watcher Startravel-80 OTA vs Sky-Watcher Startravel-80 AZ3..
