Description

Bought this 1981 Orange tube C8 for $300. It's in excellent condition. Not a scratch on the tube, mirrors and corrector are perfect. Focuser is smooth with minimum image shift. Exhibits typical field curvature with stars looking pretty bad once you move a short distance from the center. I had an Astro-Physics telecompressor on hand to reduce the focal length to about 1300mm and a Baader Steel Track to help with the focusing. Unfortunately, the AP telecompressor does nothing to flatten the field. I wanted to experiment with the scope before iinvesting in a Starizona field flattener/ reducer which costs more than the scope ($400). I'm wondering if the Starizona piece will make a significant improvement? Most say buy an Edge HD and be done with it. But maybe it's worth investing a little in this scope. I'm not a Pixel Peeper so perfection is not my goal. However, fun is . Feel free to comment.
