AM 1316-240 AKA ESO 508-43
Hydra

I have been going through Arp and Madore’s Souther Peculiar Galaxies Catalog looking for objects that I can observe from my home in Fort Davis Texas. I was surprised at how many objects are within reach from my +30 location. AM 1316-240 is a compact group with four galaxies that got my attention. I really like compact galaxies groups and wondered why Hickson did not include it in his catalog.

The big edge on galaxy is ESO 508-43 the fuzz ball to the right is LEDA 790153 the small edge on on the top left is 2MFGC 10641 and the little galaxies below it is not cataloged. I was surprised that this group is higher than M83 and should be in reach for most observers. I have not tried this group yet but plan on observing it when the moon gets out of the way. I hope you will try it too. I do not know of any observations of it yet. I will post what I see next week.

Give It a GO!
Good Luck and Great Viewing

That's a great find, Jimi..!

The li'l one is PGC4681588 / 6dFJ1319096-242505. Here it is in Hyperleda and it's mentioned here, too, but that seems to be all the info to be found.

I will piece together a guide tomorrow.

Jimi didn't mention the location but the AM 1316-240 group is only 16' W of the spiral NGC 5085. Also nearby is the overlapping Arp-Madore AM 1316-241[/URL] pair (HST image) and more.

Thanks for pointing that out Steve The area is really rich in DSO's.
