Hi All,
Since nobody has posted anything lately, I though I would take a night out and image a few galaxies around the Leo area. M100 is one of my favorites. This is a combination of 15 x 10 minute exposures. The skies around here were transparent, but heavily light polluted. Nevertheless, the faintest objects visible in this exposure, just above the noise level are 18.5 mag galaxies. The faint outer arms of M100 are just visible in this exposure.
The image shows M100, NGC 6312 to ward the upper left, two 14 mag galaxies NGC 4323 and NGC 4328 to ward the right and upper right, IC783 at 13.8 just being cut off toward the bottom left, and a number of others which don't seem to appear on my planetarium program.
There are some gradient lines at about 45 degrees, which originated in the camera. The image did not have flat field subtraction, thus the gradients.
