Tonight I was rounding off my extragalactic NGC and IC objects in Cygnus TODO list and moving on to Lacerta, when I observed two galaxies that don't have an NGC/IC/UGC/MCG/PGC designation.
The first one turns out to be 2MFGC 14852 near NGC 6783 which came as a surprise because I expected to see one galaxy but noticed two and Skytools couldn't tell me what it was. When I got home I checked against Simbad, NED and HyperLeda and they all contain this galaxy. Unfortunately only J, H and K band magnitudes are available, which explains why it's not in the Skytools database. I actually made a digital sketch on my phone to be able to identify the galaxy once I got home. See the attachment. NGC 6783 is the lower smudge of the two.
The second one I noticed when comparing my view of NGC 7223 with an image found on Google. I do this often once I have observed an object to ascertain that I haven't missed any details and I do this after not to be biased by any image. I noticed the galaxy 2MASX J22100570+4101441 at the place where I thought I saw a faint star. Closer inspection indeed revealed that the "star" is an extended object. Again, only J, H and K band magnitudes are available.
