Thanks guys. These are quite interesting critters that seem to have captured my interest right now. Hopefully when the jet stream settles down and we get some better seeing, I'll be able to image some closer doubles.
At the moment, if I try to capture anything below about 50 deg altitude, I can see the blue and red part of the star light separating due to atmospheric diffraction and this makes it difficult to get a clean split between the components.
Cheers
Dennis
