ASTRO: M110

In cleaning the hard drive I found I'd retaken M110 in color and even
processed the image but I'd filed it as NGC110 and it got lost. But
that was a year ago and my color processing skills were lousy back then.
So I started from scratch and found that I had far more faint detail
than I realized. When I posted it as a black and white image in the
fall of 2006 I saw now hint of a tidal arm and M31 was well out of the
image to the lower left. When I retook it for color using 10 more
minutes exposure time it didn't look any different. But when I
reprocessed it the other night I found the whole lower left part of the
image shows a faint tidal arm running down to M31. Outlying stars of
M31 show up at the very left edge running up the edge a short way. This
is far beyond the normal edge of M31. Shows me I've learned a lot about
digging signal out of the noise in the last year.

M110 seems to have a surprisingly blue core. With the reddish brown
dust in there I guess new stars could be forming. I checked the DSS
plates and they too show a brighter core in the blue than the red so
assume it is real.

Great picture Rick. I also got a blue core in M110 when I did a colour
version a few years ago.
