Hi to all

I would like to have two concentric circles (instead of one) in the
guide's screen: One for the viewfinder (at level 5, 7 deg. ) and
another one for the eyepiece (30 minutes). How to get the second one?
Actually, I use that ccd (square frame) as a simulation of the
eyepiece, but it would be better to have a round region..

Any idea?

Thanks
