Hey folks,

I'm pretty sure my account here on CN will be listed as a vendor, but this is a personal sale of a beautiful Thomas M Back designed APM 130mm Refractor. 780mm of FL will give you a pretty fast scope at f/6. This scope delivers at the top end for astrophotographers and it's currently rigged for dedicated AP. This sale comes with:
  • The OTA - ($5700 new)
  • A 3.5" Feathertouch focuser assembly with rotating captains wheel (FTF3545B-A) - ($885 new)
  • A Feathertouch stepper motor (MSM35) - ($295 new)
  • A matched flattener (WO FF68) - ($568 new)
  • A dedicated Pelican case with rollers (1650) - ($299 new)
  • A free copy of SGPro or Free Upgrade if already owned (~$100)
Selling this as an AP package for $5499 + $50 shipping (I will cover the rest of this cost)

Detailed specs here at APMs website

  • This scope has back focus set for a QSI wsg camera. If you don't have one, you will need to reassess to spacer on the camera side of the flattener.
  • Aperture lens is pristine... no attempt ever to "clean"
  • Will have this professionally packed
  • Please let me know if you have questions
