Product description

The customer order states the following:
I took plenty of time to perform a thorough alignment, starting with centering the focuser and continuing with star alignment. The telescope offers all the necessary adjustment options via 3-point adjustment on the focuser and the primary mirror.
I purchased the telescope 8 months ago, and 4 months later, the Mewlon 12"
offer arrived.
The receipt is available.
Due to the open design and the absence of a corrector plate, the telescope cools down very quickly. The annoying tube seeing found in SC systems is not present here.
