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 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.
