I have a celestron vixen 90mm f/14.5 - very sharp on planets - massive collimateable lens cell and all metal construction. Very smooth focuser - nothing like todays chinese refractors. I would be interested in swapping for a televue ranger (have been offered $425 for it so think this is reasonable) or maybe a sharp celestron vixen C102 OTA or something interesting. May sell outright if a reasonable offer is made.
Thanks for looking.
