I'm running at f/6.4 with a focal reducer. I don't have a permanent setup so f/8 is just too slow for me.
I have a FT focuser that came with the scope but I'm about to swap it for an Atlas.
Cheers,
Rick.

I am told Blackboard paint is good. There was an excellent thread I read on a Yahoo Group where this guy had researched various matt black paints and come up with the best. Perhaps a google search for telescope matt black paint or similar may pick it up.

Thanks Greg, it looks as if I may have to strip it all down and redo the matting inside the scope as its that sort of attention to detail that can get the most out of the scope. The gradient in the first post was actually due to my bad as I neglected to do flats for the RGB and only did it for the Lum channel. Too used to melding an OSC and Lum as before. I ran it through PixInsight LE and removed the gradient in the RGB and below is a fixed version. It wasnt meant to be a final shot as I was really looking at the flat field etc and really wanted to show IIS members how it was right out of the box as it were. See the attched image for a correction.
