VV 161 (UGC 3274) - Orion

[Mike JW]

A few nights back I was doing a tour of the VV galaxies in Orion.

This image fascinated me. I have circled the VV galaxy in red ( I am not sure if it should include all of the group or just the two I have circled.

The group has 6 members (one is partly hidden by my red circle). The grey circles are around positively identified PGC galaxies, as faint as mag 18. However quite a few other grey fuzzy spots are shown - I suspect they are galaxies and not faint, out of focus stars. Orion is not a constellation I would naturally go hunting out galaxies. Mike

This is a very nice grouping. In fact, it is the central part of Abell-Corwin-Orowin galaxy cluster 539. Here's a shot from some time ago, complete with hot pixels... It really needs an even large field of view.

Thanks Martin - handy to see the wider view. Thanks for the link, too much too easily download for our rather poor broadband link - pity. Mike

That's a mighty haul of galaxies.

Mike - what are you using to identify the PGCs in your shot?

I use a mix of Sky Map 12 and Sky Safari to identify the PCGs but my shot has galaxies that are outside of that catalogue. Mike
