Object name: ARP229
Designation(s): ARP229, NGC507GROUP, NGC0494, NGC0495, NGC0496, NGC0498, NGC0483, IC1680, IC1682,
This is my second try at the NGC 507 group. The first attempt was centered on NGC 507 as part of my project to image the Arp Galaxies. But that missed much of the group to the north. Also, the color data with the original was rather poor. This time I got good color data but seeing wasn't so hot. Since the framing is very different I couldn't use the good color data with the better seeing of the first image. The group is located in the northeast corner of Pisces, near M33. Its distance is listed at about 250 million light-years by NED though this seems at odds with the distances of its members. In fact, NGC 507 which appears to be the Big Cluster Galaxy of the group but is shown at only 210 million light-years. In fact, the redshifts of the galaxies NED considers to be group members seems rather centered about this value with only one in my image greater than 250 and most in the 200 million light-year range. Normally I'd not include the distance values in an annotated image but because of this discrepancy did so in this case. A question mark for distance means the galaxy had no redshift value but appears it may be part of the group. A couple oddball blue galaxies weren't in NED at all as galaxies. They are listed only with a question mark. While the data release 8 of the SDSS covers this field that hasn't yet been added to NED so many galaxies are omitted. These two, however, appear highly distorted and may be small members of the group that didn't fare well in interactions. One, northwest of Arp 229 is a very blue irregular mess with several bright star clouds. The other to the northeast of Arp 229 is drawn out into a streak similar to an edge on galaxy but has a dim area a bit southeast of center that shouldn't be in a true edge on galaxy. Is it two galaxies? (Edit: NED now includes these. The NE streak is GALEX J102409.16+332342.7 and the NW mess is GALEX J012320.62+332049.5. Both are identified as a UltraViolet Excess Source but have no distance information.) In the Sloan image which includes near UV light, the lower section is a lot bluer than the upper. That is just the opposite of my image. This would indicate the lower part is full of super hot blue stars emitting mostly in UV light I can't see as my filters block UV light. My corrector plate can't handle that color which would fuzz up my images so I use a filter that limits my coverage to the visible part of the spectrum.
