Catalog Errors
NGC 599
For many years, the professional catalogs had this galaxy incorrectly identified as Arp 4, and this error carried through to a number of the planetarium and chart generating programs. While it is a somewhat unusual galaxy, it is not Arp 4.
MCG-6-2-22A, The Cartwheel
10-inch Newtonian, StarlightXpress MX716, 46 minutes. One or both of the companions northeast of the primary apparently passed through it, clearing out much of the interior and initiating the ring of star-forming regions.
2x detail
This galaxy is in the field with Arp 253. The image is a 2x detail. There are hints of a merger of several objects but it is pretty hard to classify.
NGC 2724 is in the field with Arp 202. This is a 1.5x detail. It certainly could have been an Arp, with the twisting and forking of the arms in the interior and the extremely long faint extensions of the arms reaching the N and S edges of this field.
The large low-surface-brightness spiral is NGC 6962. Very similar to Arp 1, it could easily fit into Dr. Arp's LSB Spirals class. The group could also be placed in Galaxy Groups. The companion to the SE is NGC 6964. Somewhat farther away to the NW is NGC6961. The triangle of galaxies N of 6962 consists of NGC 6967 (the largest of the three), NGC 6965, and NGC 6959. I'm not sure which of these, or of the other galaxies in the field, are considered part of the group.
This image was made with the 10-inch Newtonian and ST2000XM, and is a 60 minute exposure. Click on this image to see a full size view. There are quite a large number of unusual galaxies in the field.
NGC 7013 is not a particularly unusual galaxy but it does appear to consist of an outer ring and a large core, with little material in between
NGC 2667 is the S galaxy in this pair of very similar galaxies. The N galaxy is IC 2411. No interaction can be seen.
UGC 9632 is in the field with Arp 136. This is a 1.5x detail from a 54 minute image. The primary is full of unusual bar-like arms and starburst regions.
