Wow, by my reckoning then you're resolving detail down to just under 2 arcsec. Seeing must have been excellent for those nights - darned impressive from suburbia!! Looks like that RCOS 10 is a keeper!
I am really overwhelmed by all your kind comments. Thank you all for that. I am really hoping that we get favourable weather for imaging in the future. The skies over Melbourne have been overcast for an eternity. Once again, thank you for your feedback.
I found trying to get a guide star through the filters to be a bit painful at times, so I sorted out the bits to get my OAG working again. With it in front of the filter I could guide much easier. Maybe this might be useful for you as well Terry?
