Good but very difficult to find star or something because zoom is so hi you cannot find anything with 6mm lens only 20mm lens use Barlow lens only for star and planet . Use Barlow to attach before mirror. It gives clear image video and images I ateched in 20mm lens when use 6mm lens only one crater see because it zoom 60x. Make a finder scope like I make and use Barlow lens direct do note use mirror. Then it works. Without find scope very difficult two find an object. 21May 2019 today I see Jupiter 3 moons buy this telescope. Total value for money.
