I'm not really sure how much to ask for this so feel free to make an offer, if my asking price is too high. If it's too low, you can offer a higher price. :-)
This is a focuser from a Celestron CR 150 Refractor. It will probably fit other 6" Syntas. It is in very good condition, and comes with the original 2" visual back and 1/14" adapter. All the screws and knobs are included.
Thanks for looking and have a nice day.
