Andy U. (Grand Junction, Colorado, United States)
Absolutely love this telescope! The glass is so clear.

ES ar102/600 with nano mount. Absolutely love it. Do wish there was info on the scope. Instructions were basic at best. Mostly pictures. The altitude does not lock down. It's all about balance. Put the explore scientific logo between the rings then push the scope forward about a inch. Will hold phone weight and not slip. Again scope is amazing. Seller is amazing! Very fast shipping. Well packed. Pics are of mars, Sirius. And the moon on a 25mm that came with it. I did split a double star in orion constellation. Blew my mind. Love it. Btw mars is crazy far away right now but I'm jacked about the picture with my cell phone.
