ASTRO: NGC 3193, 3190, 3187, 3185
I processed this before the power supply died and never moved it to this
computer before its demise. Then in all the ruckus forgot about it. Ran into it cleaning out old files this afternoon. This is one I did last spring with the 6" f/4. It did go a bit deeper. F/4 and the higher sensitivity of the ST-7 shows as the faint extended arms of NGC 3187 were much brighter in the 6" shot. But the 14" gives far more detail. Next year I'll give it a lot more time From top to bottom NGC 3193 is the featureless elliptical, NGC 3187 the faint peculiar barred spiral with the elongated arms, NGC 3190 the bright peculiar spiral with the tilted dust lane and NGC 3185 a ring type barred spiral. Looks like 3190 and 3187 may have tidally interacted some time in the past. But the red shift data would indicate this is not likely. 3190 is the most distant of the 4 by red shift at about 90 million light years. The other three are all about the same distance however with 3187 at 64 million light years, 3193 at 59 million LY and 3185 at 53 million LY. In any case I've always enjoyed these four visually in my 10" scope. There are lots of other faint fuzzies in the background. 14" LX200R@f/10, L=9x5' RGB 3x5' 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". |

i really like those galaxies rick
3187 is really nice "Rick Johnson" wrote in message ... I processed this before the power supply died and never moved it to this computer before its demise. Then in all the ruckus forgot about it.

Very impressive shot Rick. This is my favorite galaxy grouping. Your
processing is very good here also...for my eyes. The colors look great. I did this a few years ago...I'll se if I can find them Joe "Rick Johnson" wrote in message ...

Rick, It's Hickson 44, so it must be springtime!! Great image of this compact galaxy group. George N |
