ASTRO: Arp 206 / NGC 3432
I'm return to Arp galaxies with Arp 206, AKA NGC 3432. I really don't
see it as much stranger than IC 4182, I posted a few days ago, which looks like a slow moving propeller that didn't make his list. Arp 206 is cataloged by him as a galaxy with "material ejected from the nuclei." That apparently refers to the blob of material at the upper left end of the galaxy as all others in this category have similar detached pieces though he has a category for detached arms that would seem to also fit. But he classed this as indeterminate between elliptical and spiral while it looks clearly spiral to me as do most others in this section of his catalog. The distortion seems caused by interaction with UGC 05983 a dwarf galaxy at the lower right end of the galaxy. The distance to this one is also rather hard to come by. Red shift data says 40 to 45 million light years though since these are likely orbiting each other this value is somewhat questionable. This seems to be one of the lesser studied Arp galaxies. At least I found very little on it. That bright star to the east has been greatly reduced as it sent a huge orange ring across much of the image making this a processing nightmare. 14" LX200R @ f/10, L=4x10' RGB 1x10' binned 3x3 (cloud and moon problems), STL-11000XM, Paramount ME Rick -- Correct domain name is arvig and it is net not com. Prefix is correct. Third character is a zero rather than a capital "Oh". |

isn't this the whale galaxy?

Nope. The whale is NGC 4631. The Whale is an Arp galaxy however. It
and its companion NGC 4627 are Arp 281 which falls under the class of "Group Character" showing "infall and attraction", whatever that means. I posted a reprocess of that one in April. it is much closer so shows lots more detail. My repost can be seen at: http://www.spacebanter.com/attachmen...tid=1862&stc=1 For a listing of the Arp catalog and the categories he used see: http://members.aol.com/arpgalaxy/arpord.html Rick G wrote: isn't this the whale galaxy?

Rick, very good picture. I have imaged this galaxy, but got nowhere near the
detail you have. Stefan "Rick Johnson" schrieb im Newsbeitrag . com... I'm return to Arp galaxies with Arp 206, AKA NGC 3432.

that's another nice image of an interesting target Rick
