I bought this GSO 2" Linear Bearing Focuser for 6" Newtonians on 5/3/19 and have been using it since shortly after that. I mounted it on a 130SLT after reading a write-up someone else did about using the regular (non linear bearing) GSO on a 130SLT. I really like it but don't think there's any way to ever make it work with the Orion Argonaut/Intes MK-67 I recently bought. So it looks like I'm going to have to get a Moonlight CR and their $50 extra adapter so this has to go... While I'll be selling my old scope, and I don't expect the buyer of that would be sufficiently swayed enough for the additional cost to make it worth selling together.

Includes a Type-0 plate
Type 0: Base Plate for 6" Telescopes - GSO
- Base plate curve diameter: 6.93" (176mm)
- Base plate dimensions: 3.54" x 3.54" (90mm x 90mm)
- Hole Spacing (center-to-center along telescope tube/optical axis): 70mm (2.76")
- Hole Spacing (center-to-center perpendicular to telescope tube; straight line measurement): 73mm (2.87")
- Hole Spacing (center-to-center perpendicular to telescope tube; measured along curve of base plate): 74mm (2.91")

Additional plates are available for other size scopes:
Type 1A: Base Plate for 8"/10" Telescopes - GSO
Type 1B: Base Plate for 8"/10" Telescopes - Non GSO
Type 2: Base Plate for 12" and Larger Telescopes - GSO
Type 3: Flat Base Plate
These plates run $17 to $23 from Agena. Full plate specs and more information can be found here: https://agenaastro.c...rd-focuser.html

Note there is 1 mark that I see. Looking at the side with GSO showing at the bottom edge on the adapter plate. Not sure if it was there before or not. I didn't notice it until taking pictures tonight.
I paid $175 just a few months ago. I'm asking $115 and that includes PP fees and USPS shipping in CONUS.
