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 (southwest) 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. 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 For a less compressed image see: http://www.spacebanter.com/attachmen...tid=1967&stc=1 Rick |

Rick,
Another amazing image as you journey through Arp's list. The color and detail are great even given the low exposure time. If I ever had doubts that binning on a long FL scope is the way to go, you have dispelled them. Thanks for sharing! --Andy
