Enjoy the Telescope. However, you put a 20% discount on the Telescope 10 days after I purchased it at full price

The optics on the ES ED102 air beautiful, absolutely no chromatic aberration that I could see, I own an AR102 which I’m very happy with also but the false color became hard to ignore. I am very happy with my purchase. I don’t want to say anything bad about this telescope because for the price it can’t be beet, excellent value for the money. If I could make 1 recommendation it would be to increase the length of the focuser draw tube, I found that I needed to use 1 or both of the extensions for different eyepiece’s, most require 1 extension but my Russel optics konig’s needed both extensions witch were supplied with this telescope so I in very happy about that.
