BIG filter wheel on a TINY scope

I was going to hold off on showing this off until the SBIG ST8300M was screwed onto the rear of it... I held off for over a week, but its finally gotten the better of me...

If you've ever wondered what an 8" diameter filter wheel would look like on the back of an 80mm telescope... Well... Here it is...

New Toys:

FLI CFW 2-7:
7 Position 2" filterwheel, Currently fully loaded with Astrodon LRGB I-Series 50mm unmounted and Astrodon 5nm Ha, SII and OIII unmounted filters...

Custom adapter between CFW and MPCC, Made by precise parts in Miami, This adapter is back focus matched for the ST8300, CFW and either the MPCC or the TV TRF-2008 0.8x reducer flattener (which have the same spacing requirements) so I can use the scope at F/6 or F/4.8 without needing separate adapters...

All this hangs out the rear of the OAG...

From what I can tell thus far, I'll be needing a longer dovetail as Its pretty well balanced now, however im sure once I add an 800g camera to the rear end it will become very rear heavy... The joys of being a metal worker..


Alex - Patiently awaits delivery of SBIG!!
