You could use the RC, I am persisting with mine. .... Is it because of the flattener that you are not using it? Or is it the baffle related issue? Or both. .

Hi Paul and thanks to you and Jase also.
The RC issue goes back to a disastrous flocking of the baffle tube in the course of which the primary became dislodged. The little grub screws that hold the mirror retaining ring in place don't actually screw into anything. All they do is slip between the threads and jam it. It's a hell of a system. Anyway the retaining ring came out with the baffle and there was nothing holding it in place. In the course of putting it away out of dust and harm's way, it started to fall out - I rescued it but only after getting a horny thumbprint on it and having to then wash the whole mirror. Of course it couldn't go back into the right alignment because although there is a checkmark on the edge of the mottor, there is no corresponding mark in the frame so heaven only knows which way it shoudl go. In the result, the alignment of the mirror went out to high heaven and I haven't ever been able to bring it back into anything like the former optical alignment (which I hastenb to say was terrific). SO now, it's a fancy tankard with a shiy bottom and will remain so until I have learnt the arts of collimating the thing. Offers of help with GSO were made but I've heard nothing and am more or less reconciled to having made an expensive mistake.
Such is life. If I knew the Latin for that, I'd make it my IIS signature. The only other person I can remember who used the expression was Breaker Morant and well, we know how he ended up.

You're right in saying that's not an easy one. I think this DSO needs a longer FL to image with.
