20 inch f 4.5 Dobsonian Telescope for sale

Post by Bsimon » Fri Sep 20, 2019 10:09 am

This one is owned by Ralph Junius, one of our PAS members and a regular at the Deep South Star Gaze. He would like to sell it to downsize to another 20 inch dobsonian with a faster focal ratio (making the new one shorter).

What Ralph has is a Night Sky 20 inch f/4.5 scope with Pegasus optics and Argo Navis. The scope also has a very nice 2" FeatherTouch focuser and a nice "orchard" ladder making access to the focuser when the scope is pointed high overhead easy. (Note - an orchard ladder is wider at the base making it steady. It has 3 points of contact with the ground making it more stable on uneven ground than a ladder with 4 points of contact. In addition the steps are closer together. This makes getting to the proper height (eye to eyepiece) a bit easier. The scope also comes with wheels and handles making transport from a vehicle to observing position a bit easier.

The optics have been compared to similar sized dobsonians. This mirror is a winner. It was recoated a few years ago.

Asking $5500 and will consider reasonable offers. Can be delivered to the Deep South Star Gaze.

If strongly interested please let me know and I will contact Ralph with any questions.
