Several techniques exist to fix this issue.

Hi Lewis. I looked around at some great images from the Vixen but the defraction spikes are going to be an issue for me I think. They look loke great scopes though.

That BRC 250 in hindsight was a beautiful scope. Its F5.

aaah...theres one on astromart..hmmmmm. Its fast enough and the FOV looks great. Reasonable fit for both the DSLR and a sony chipped camera by the looks of things at least for the targets I am interested in.tempting but need to do some more research first. The obvious question would be why you moved yours on?

Thanks. I have been looking at the BAZ thread and will keep looking at that.
