Amazing Clarity This is my first telescope. I have been using the 250pds for 2 months for viewing and astrophotography. Its not too bulky and easy to handle on your own. I have been amazed at the clarity of the objects that I can see and the photographs I've taken. The two speed focuser is great to use. (18/08/2017) Neil L - Bridgend, South Wales
