ASTRO: Copeland's Septet
Another I've saved from moonlight though it wasn't as difficult a case
as some I'm still working on. This group of 7 NGC galaxies +2 others is located about 400 million light years from us. NGC 3753 is the distorted one in the center. It is also known as Arp 320 though that also applies to the group as well it appears. A finder chart based on the POSS I plates of the NGC members is at: http://www.ngcic.org/dss/n/3/n3753.jpg Note the plate defect above the label for NGC 3754. It isn't a disappearing galaxy in my shot. Also in the group is PGC 036010 below NGC 3748 and MAPS-NGP O_376_2857526 above the G in the label for NGC 3745. So it should be called Copeland's Nonet. Though these last two are nearly magnitude 18 so likely out of reach visually unless you have a very large scope like a 30" Obsession. The asteroid to the lower left (southeast) is (30376) 2000 JE65 at magnitude 17.7 14" LX200R @ f/10, L=4x10', RGB=2x10' binned 3x3, STL-11000XM, Paramount ME BTW it is snowing again with 6 to 12 more inches predicted for tomorrow! March winds bring April blizzards seems the song for here this year. 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". |

Nice shot of this group Rick!

Further checking of red shift data shows the two red galaxies at the
bottom of the image, one on either side of the K2 SAO 81815 are also likely members of the group. So what is the word for a group of 11 -- undectet? The blue galaxy between the two reddish ones isn't listed in NED or SIMBAD. Other reddish galaxies in the image are either not in either or have red shifts other than expected for cluster members. But I only checked red ones and few were in either database. Rick Rick Johnson wrote: Another I've saved from moonlight though it wasn't as difficult a case as some I'm still working on.

Make that SAO 81915. I can't type straight.

Great detail in these small ones. Can it be that you had better seeing for
these recently processed images than usual? Detail is really outstanding in some of your last shots. Stefan "Rick Johnson" schrieb im Newsbeitrag ...

Yes. Guess that's the universe paying me back for all the moonlight I
have to image through. I'm starting to be able to process it. Previous to this spring I'd had only two nights with seeing under 3". These have all be around 2.5". But we're now melting out of out third major storm in one month. Total snowfall is close to two meters this month. Annual average is one meter for all winter. We were at about 3/4 meter for all winter then spring hit. It's snowing in the state now but not here -- yet. That's to hit Friday. Course then it will be a May storm.
