ASTRO: UGCA 92 Another few have ever heard of
UGCA 92 is a member of the highly obscured Maffei group. It is located
in Camelopardalis some 6.5 million light-years away. Distance to these obscured object is very difficult to determine. This is a very approximate value In any case it is very nearby. Redshift at such close distances is useless. In fact it is blue shifted. NED has 6 different distance estimates listed which range from 2.6 to 10.1 million light-years with a median value of 6.5. It is classed as Im? which is an irregular of the Magellanic type, maybe. Just not enough is seen through the gunk. NED lists 11 other galaxies in my field, none with even magnitude estimates let alone redshift data. All are from the 2MASS survey. Looking closely I see far more in the image. Apparently they weren't bright enough at 2 microns to make the survey. The lack of galaxies is, of course, due to the heavy extinction in this part of the sky. The field isn't far from the Heart and Soul Nebulae to give you an idea how obscured this area is. 14" LX200R @ f/10, L=8x10' RGB=2x10', STL-11000XM, Paramount ME Rick -- Prefix is correct.

Rick,
you even managed to capture fine detail in this obscured galaxy! Stefan "Rick Johnson" schrieb im Newsbeitrag ... UGCA 92 is a member of the highly obscured Maffei group.
