Celestron 9.25 Edge HD on CGX Mount
All arrived safely. Product well packaged. All parts present and set up pretty straight forward. First night out seeing was patchy due to some cloud and a bright moon but what was visible was clear and sharp right to the very edge of the field.
Great Service
Great service from Alex, prompt, helpful, knowledgeable. Fast delivery. Very happy customer.
Great service from Alex
Thank you for your help in getting the scope and gear. We really appreciated your advice and tepid response. The courier for the tube wasn’t so great: they just dropped the box outside the depot sometime overnight for the depot office to find it there at opening.
