Object name: NGC5371

Designation(s): NGC5371, HCG68, NGC 5353, NGC 5354, NGC5350, NGC 5355, NGC5358,

I took Hickson 68 back in 2008 but missed picking up NGC 5371. My techniques in 2008 were poor compared to today. Still, for some reason, I put Hickson 68 too low in the new field missing the edge of the odd plume of NGC 5353 as well as an interesting UGC galaxy but did pick up NGC 5371. Why I framed it poorly after the first goof I don\'t know but I managed it. Thanks to my technique being rather poor in 2008 I found combining the two wasn\'t working well. The older image was just not good enough to combine without the obvious change in noise level. So, for now, this will have to do.

This field is located in eastern Canes Venatici with all major galaxies at a distance of about 125 million light-years. So it appears NGC 5371 may be part of the same \"local group\" as the members of Hickson 68. Though the redshift distance to NGC 5371 varies quite a bit from the non-redshift distance of only about 93 to 110 million light-years. If that is right then it isn\'t related after all. In fact, I rather doubt its redshift distance is correct. Assuming the 125 million light-year distance to the Hickson 68 group then its spiral member NGC 5350 is some 130,000 light-years across and NGC 5371 is a whopping 220,000 light-years in size. Even moving it to 93 million light-years, the median non-redshift distance at NED it is still a very large 160,000 light-years across. The higher resolution I get for it also seems to indicate it is closer than its redshift says.

NGC 5350 shows some faint drawn out arms indicating it is interacting with its companions. The SO galaxies NGC 5353 and NGC 5354 share a common halo indicating they are certainly interacting. The Starburst nature of NGC 5350 and the AGN status of NGC 5353 and LINER status of NGC 5354, while not necessarily due to interaction likely are in this case. While Hickson 68 is listed with 5 members, all NGC galaxies there\'s a 6th apparent member, LEDA 099754. I don\'t know why it isn\'t considered part of the group -- too small? Unfortunately, glare from the K5 6.5 magnitude HD 121197 makes seeing the full extent of the plumes of NGC 5350 difficult. It must have hit a speck of dirt near the CCD to have created the glare spikes it did. This image was taken before my annual spring cleaning of the optics.

Arguing for NGC 5371 being closer than its redshift indicates are the HII regions with strong H alpha emission I am able to resolve in it without the aid of H alpha data. They show up as the pink objects along its arms. I\'d not expect that at the greater distance and find it surprising even at the closer distance estimate.

NGC 5350, 5353, 5354 and 5355 were discovered on January 14, 1788 by William Herschel but aren\'t in either Herschel 400 list.
NGC 5358 was found by Edouard Stephan on June 23, 1880 having been missed by both Herschels for some reason.
NGC 5371 was found by William Herschel on the same January 14, 1788 night as 4 of the 5 Hickson 68 members. It is on the Herschel 2 400 list. It was later found by John Herschel on March 18, 1831 and due to a position uncertainty listed as NGC 5390. Since there\'s nothing at his position for NGC 5390 its identity as NGC 5371 isn\'t certain but most catalogs list them as the same object, even SIMBAD which sometimes rejects such probable duplicates.
