    This galaxy field really is a playground for active galactic nuclei enthusiasts!

    Last March I observed Markarian 421 with my 20" Dobsonian at 256x magnification and noticed a stellar nucleus surrounded by a faint glow. I did not see or did not pay attention to PGC 33453. But I noticed the quadrangle consisting of the two bright stars, Markarian 421, and the diffuse UGC 6140.

    Please find attached my sketch of the whole galaxy field I observed back then. It includes two more AGN host galaxies (PGC 33514 and PGC 33518).
