Object name: NGC1169

Designation(s): NGC1169,

I spotted NGC 1169 on many web photos taken with wide angle lenses of Comet Holmes. It showed as a faint yellowish blob on these photos. I decided to see what it looked like. This is taken through the Milky Way's dust lane that blocks light from most distant galaxies. It is rather surprising to find any in this part of the sky. In fact, it is often called the "Zone of Avoidance". Galaxies don't avoid this area, they just can't be seen through it. Apparently, there's a hole in the dust in this zone that allows this guy and many more distant ones through. The clue there's still a lot of dust is the yellow color. Spiral galaxies normally have very blue arms caused by the newly formed hot blue stars that make up the arms. But Milky way dust scatters most of the blue light preventing it from reaching us and turning the galaxies toward the red end of the spectrum. Note this has nothing to do with "Red Shift". This is the same scattering of blue light that causes our sun to appear orange or red at sunset. Seen through a lot more atmosphere the blue light is scattered away turning it red. All the galaxies in this photo have nearly the same yellow-orange color indicating the dust is pretty much the same density and of the same particle size all across the image. NGC 1169 was discovered by William Herschel on December 11, 1786. It is in the second H400 observing program.

All galaxies in this image are distant. Closest, of course, is NGC 1169 at 100 million light years. I like the 4 to the upper right. 3 are nice thin spirals and 1 a face on spiral. The three thin guys from bottom to top are UGC 02496 at 300 million light years, LEDA 213150 at 528 million light years and LEDA 213153 at an unknown distance. I found no info on the distance to any of the others. The face on in this group of apparently unrelated galaxies is LEDA 213151

The barred spiral just above and left of 1169 is AGC 130456. Above it near the top is AGC 130457

The only other one I bothered to look up is the one at the far right below center It has a mouthful of a name HFLLBZOA K547
HFLLBZOA stands for Hav, Ferguson, Lahav, Lynden, Bell Zone of Avoidance Galaxies.
