Clockwise from top left is NGC941, NGC936 and down the bottom PGC9394.
The barlens morphology of 936 is pretty cool - there's quite a few recent papers on this in the literature. No idea what scrunched the other two up, though! In the attached thumbnail you will see two circled quasars - the one on the left has a redshift of 2, meaning the light is about 13.7 Billion years old...
Total of 4 hours of LRGB, 5 minute subs (x12 each filter). Scope is the ASA16"f3.6 on the DDM85, using a QSI683. The field isn't actually very colourful, as it turns out...

Interesting field, Andrew. I hadn't seen it before.

That's a really interesting field! Well chosen and well researched. Trish and I would love to have a go at it when our camera comes back from hospital.
