Very well done, Adam. They are small and faint and not easy. Lots of detail and colour.

I did these two this time last year myself, they are a lovely pair and you have captured them quite well Adam. I love the ring of star formation around the core of NGC 6935 :thumbsup: it came up really blue in my data.

Very nice Adam. That's the sort of stuff I'll be after.

Nice image Adam. The resolution is very nice too. I can see some very faint outer arms around NGC6935 which might be more visible with more time.
