Amazing telescope. I have used a number of telescopes and this is one of the best based on flexibility, ease of use and performance. When mounted on a simple Eq. tracking mount I am getting better pictures than with my C925 that has been a significant source of disappointment. For this price, there is no better telescope in the market.
