ASTRO: NGC 4435 and 4438 The Eyes
Still working on disturbed galaxies. Unfortunately, seeing was very
disturbed that night, 4" so this is a pretty lousy image. It will have to do for this year. First try was lost due to my frost problem, though seeing was somewhat better it wasn't great and those images were so frost covered they can't be salvaged, by me anyway. NGC 4438 is the really disturbed one. NGC 4435 is above it. Other galaxies in the field are PGC 40958 low, left of center amid a triangle of blue stars. IC 3393 in the lower left corner. Hardest to find is PGC 40981 that forms a tight pair with a dim white star on its right. It is above and right of a pair of blue white stars. Above it and to the left a bit along the top edge is PGC 4107. The fuzzy object midway up the left edge is a star not a galaxy. PGC 40913 is the large fuzzy blob straight below the nucleus of NGC 4438 but still seen through the cloud of tidally ripped stars. The blue galaxy near the upper edge on the right is IC 3355. There are lots of other faint fuzzies in the image I didn't look up. 14" LX200R @ f/10, L=8x10' RGB=2x10' all binned 2x2, 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". |

Rick,
actually before I saw your quote on the seeing I was willing to write that this is one of the best "eyes" I have seen so far :-) It certainly is a very beautiful image. You really got the hang of colour imaging recently. Stefan "Rick Johnson" schrieb im Newsbeitrag ... Still working on disturbed galaxies.

Everything I read said this set up would work best at 5 minute sub
frames but I've found that since moving to 10 minute subs I'm getting far better color. Seems to need the 10 minute subs on the luminosity frames as well. When I tried just 10 minutes on the color frames it didn't work much better than with 5 minute color frames. Nor if the luminosity was 10 but the color 5. That was better but still not what I'm getting with both at 10 minutes. Problem is I have such a wide fov that I catch a satellite in at least one of the frames, usually three or 4 of them. Same with the 5 minute ones but I'd just retake the frame without much loss to my time line for the night. But redoing half the 10 minute frames only to find yet more satellites is playing havoc with my planning. With a GEM I have to plan around the meridian. These satellites are driving me nuts. My ability to clone them out is pretty rotten though I have succeeded a few times when the star field was star poor.
