Galaxy gems in Antlia - close up of core detail added

Just got back from a 3 night cruise on the Pacific Pearl - what a blast and fantastic experience (t'was a comedy crusie...man ), already deciding on the next cruise

Anyway...last Tuesday night I managed a few hours of darkness on a super hot night, the FLI was a godsend again as it managed to juuuust hold -30C while it was still hovering just under 29C ambient when I finally started imaging at 10.45pm - sheesh!

I imaged the beautiful nearly face on spiral galaxy NGC 2997 in Antlia - a reasonably small to modest sized and faintish galaxy (8.5' X 6.5' surface brightness 22.5mag/sq arc sec). Not as much exposure as I would have liked so I composed a sythetic Lum from the RGB (all binned 1X1) and added that to the megre 80min of Lum data I gathered.

IT looks pretty lonley sitting in a 1.6deg X 1.6deg field but of course..if you look closely the field is full of many distant galaxies!

See the 100% resolution crop of NGC 2997 in Antlia HERE

See deep inside the galaxy core HERE approx 5' X 5' FOV and even deeper in HERE

And of course..I have put together the usual album of 100% full frame to highly zoomed in close up variations Here

Can someone identify what looks like a ring galaxy visible through the galaxy arms..? - see super zoomed crop in the album.

Man I had fun on the cruise, maybe I will trade in my astroimaging a little and go on a few more cruises
