Hi Slawomir and Allan, thanks for the reply. I've thought about the OAG solution, though with the current focuser it'll have to be pretty thin to fit in there! I've been having a look back through my imaging library at various imaging sequences - and it's an intermittent issue that so far doesn't appear to be strongly connected to particular tube orientations. I might even plot the orientations up to see if there's a spatial pattern! So while that doesn't rule out anything yet, I'm going to closely explore the securing of the camera at the focuser, and the securing of the primary mirror, because some nights it's been not much of an issue at all. Have to eliminate the simple solutions first, and yes I'll learn a lot more in the process...
If it continues a big problem, then maybe OAG is the way to go!
