A well kept 4" Criterion 4000 SCT OTA that just doesn't get used since getting a G-5 scope. Corrector plate and mirror are perfect, no scratches, holds collimation well. 1/4x20 tripod mount on the bottom of the tube. This is a great astro/ spotter/camera telephoto setup, $165. Shipped CONUS, paypal transfer accepted.
Thanks for looking!
