Астрограф Celestron RASA 8 дюймов f/2 Rowe-Ackermann, Шмидт, оптическая трубка (только OTA)-91073

The seller quickly sent the package, but the track was not tracked. Delivered in 3 weeks. There are a lot of scratches on the metal part of the corrector. There is dust inside the corrector that cannot be removed. Looks like metal parts was used or repaired. Dust is also present inside the tube, on the input corrector and mirror. It is also impossible to remove it without disassembling the tube. The seller did not help to solve the problem. Replies for a long time, once a day. The seller also promised to send me photos taken before sending, but he never sent them. I was not happy with the purchase.
