Here are parts from a SkyWatcher 150mm f/8 achromat refractor. Identical to Celestron CR150HD equivalents. No optics included!
Non-adjustable objective cell with element retaining ring, dewshield, & caps. Sould fit any of the Synta or R.R. 150mm dia. achromat objectives.
2" focuser with dovetail 50mm finder mount, and AstroSky 2.5" dia knurled aluminum focus knobs. The drawtube has 3 internal baffles for an f/8 system. I de-gunkified it, relubed the rack with Slick50 grease, and replaced the crappy nylon drawtube runners with UHMW "Slick Strip", so it's super smooth and cycles concentric & true.
I'm thinking $160, including USPS Priority Mail to the lower 48. I prefer Paypal.
