Supernova SN2009lb in the distant spiral galaxy UGC 2944 (PGC 14418). Note the many background galaxies. I suspect that many of the "stars" in this image are actually the cores of unresolved galaxies. The discovery magnitude of SN2009lb was 17.3, and I have not yet calculated this image.
This is somewhat of a "test" case to see the minimum number of files that can be used to get an image. Sigma Beta needs a minimum of 3 files, so this was three each in LRGB. The L files were 10 minutes, and the RGB were 3, so the entire image took less than an hour of open shutter.
(And I can see hints of the column discussed in the previous post near the bottom.)
