Thank you guys.... Night sky, Gary, Zane, Ric, Mark S, Scott, Lester and Louie.
Has been 3 months from ordering things to finish. You learn a little more patience with building such projects but in the waiting it's a good time to think and rethink things.

Mark, I'm using the MPCC corrector. It does seem to do a good job with coma, but I hate the way these sit in with the compression ring. I have to get it spot on, 90 degs to the imaging plane... and it's never consistant when reinserting the ccd/ corrector to the focuser. A threaded model would have been much better I think. But I guess I'll have to get it tegether better.
Zane, I beginning to know what you mean by tinkering... the primary cell I made I hope to wil do the job. There was only 2 options with the conical primary. The carbon fibre setup by Dream were way too expensive and the other was an alluminium design. I'll see how my humble cell goes for the time being. Early days.
Thanks heaps for your kind comments. Hope to get some deeper results soon.

Cheers
Rich
