NGC 7331 et al.
I did the Deer Lick group back in my black and white days in fall of
2006. I wanted to do it in color but weather this fall has been horrid. I finally sort of got it low in the west. Took a lot of work to get much out of it that low. Seeing was far from what I'd have liked that low. But until next fall it will have to do. Does anyone know the source of the name Deer Lick Cluster? Seems odd to me. 7331 is about 49 million light years out and about 30,000 light years across so small compared to our spiral though rather typical. The rest in the group are over 100 million miles away, some 300 million or so. They must be really larger. Trying to ID the galaxies in this group I found several NGC objects that were just single or double stars though some versions of the NGC have assigned their numbers to other galaxies in the group that didn't make the NGC. Makes it all very confusing. Using Simbad for NGC 7325 6 and 7 gives a different result than using NED on the DSS for instance. Simbad seems to go with the original NGC visual observations by Rosse. I rotated the image so east is up. That seemed to show the apparent warping of the disk of NGC 7331 better than leaving it on edge with north up. I have it back on my "good seeing" to-do list but it will have to wait for next season. The flare at the lower right is just a star hitting the edge of the CCD. 14" LX200R @ f/10, L=4x10, RGB=2x10, STL-11000XM, Paramount ME -- Correct domain name is arvig and it is net not com. Prefix is correct. Third character is a zero rather than a capital "Oh". |

i always admire that galaxy set
nice image too Rick "Rick Johnson" wrote in message ... I did the Deer Lick group back in my black and white days in fall of 2006. I wanted to do it in color but weather this fall has been horrid.

That would indicate two words is the correct version. Thanks for the info. Rick -- Correct domain name is arvig and it is net not com. Prefix is correct.

Exceptional image Rick,
as i know it's extremely difficult to gain all these details on one of the most beautiful galaxies (my favorite indeed). I had problems with my internet provider as it doesn't deliver me all newsgroup posts, i have to download messages with space banter : http://www.spacebanter.com/forumdisplay.php?f=25, that's what i did with your pic.

Thanks much for that link. I'd been using Usenet Replayer but it
suddenly stopped updating. I didn't know of this one. You might make that link a new post so others see it that aren't following this thread.

Beautiful image Rick!! There's even some really tiny background galaxies sprinkled throughout the image. . Trying to ID the galaxies in this group I found several NGC objects that were just single or double stars though some versions of the NGC have assigned their numbers to other galaxies in the group that didn't make the NGC. Makes it all very confusing....... On the NGC/IC Project website the NGC errors notes cover this area extensively. Most of these galaxies ended up in the NGC from 19th Century contests on who could find the most fuzzies. This group was discovered by a guy using a 15-inch doublet refractor and I guess he got a little too "creative" with his list of nebulae. Last October a friend and I spent about 20 minutes going for this group with my Obsession 20 from a very dark location (PA's Cherry Springs 'dark sky' State Park) and we were able to get all of them (plus the nearby Quintet also) but I could see how someone working with poorer optics could mistake some of the double stars in the area as 'fuzzies'.
