A difficult faint galaxy near the bright star Beta Andromedae. Lots of little galaxies in this area. The full field shows about 75 faint galaxies scattered thoughout.

Total exposure 30 minutes LRGB, 305F3.8 astrograph, QSI 583 camera, Baader LRGB filters. There were lots of filter reflections that had to be dealt with unfortunately, but I did want to show the stars and galaxies near the star, which were quite evident in the L image. I would love to see someone develop better sharp cutoff filters in the future. Unfortunately the camera cover glass has only a single layer coating and causes most of the large halos by interaction with the filters.

Rolando,

I plan to use my Mewlon 210 (2415 mm focal length) on Abell 13 in Orion. Look into it and I suspect you will be pleasantly surprised as to the situation with Abell 13. wink

Anthony.
