I am looking for a Celestron/Vixen C102 4" refractor with excellent optics, rings, and preferably a 2" focuser, although this is not absolutely necessary.
Excellent optics means nearly identical diffraction rings inside and outside of focus, little color on focused objects, and no coating blemishes or scratches. The tube can be scratched up since I can fix that myself. Let me know what is out there! Thanks for reading, Bob.
