Celestron Black C90 Astro

Wonderful little grab n go these older C90 Astros. This telescope has been very well loved over the years. The optics in this particular example are fantastic. Beautiful star test either side of focus. The helical focuser is smooth for easy and precise focusing. Other than a couple tiny paint chips on the dew shield the cosmetics are excellent! Not even a scratch on the finderscope. Corrector, primary and secondary spot are exquisite for its age. No degradation of primary coatings. RA and Dec locks work just fine and RA tracking is right on. Original accessories are .965" and also in excellent condition.

Drive-base mounts to standard 1/4 x 20. Celestron Tripod is not included in the sale.

Issues of note
1. The 20 oz counterweight is NOT original. Custom-made for this scope.
2. The finderscope bracket is NOT original. It is metal and slightly larger than the original bracket but works quite well and looks nice.
3. The metal dew shield threads onto the scope. I've left the dew shield on for the most part because taking it on and off poses a bit of a challenge matching the starting point of the threads. The threads are not stripped or anything like that it's just a delicate touch is needed. I have done so many times but easier to just leave it on.
