Remarks:

Celestron’s “Skymaster” comes in various versions, both in terms of configuration (8×56, 15×70, 20×80, 25×70, 25×100) and performance (20×80, “Pro” 20×80). Pricewise, the version 20×80 is positioned in the lower part of the 20×80 market, and that reflects the performance level, see the review mentioned below. The sweet spot is quite small, and CA correction is not fantastic. But you can still experience some very nice observations under the night sky.
