A full frame camera suffers from vignetting even with a 2 inch focuser. I managed to pick up another Astro Physics 2.7 inch focuser and had Luke Bellini from Starstuff make an adapter to suit the 150mm F5 Achro. He also made two adapters that allow me to connect Borg bits to either focuser without having to use a 2 inch nose piece. The only thing now that even starts to limit the clear view of the full frame to the whole of the 150mm objective is the 48mm filter near the camera. The Borg bits have an ID of 53 to 55 mm.

I am getting a side by side unit to hold all of my scopes from Starstuff. This will allow the use of the fridge with either the 100ED or 150mm achro and allow rotation to get better framing.
