Description:
I've sketched this fantastic trio of galaxies during the Meteor Star Party 2009 in Tarján, Hungary. The two larger ones are the face-on NGC 7769 and the edge-on 7771, both with softly brightening cores. Next to 7771 a small fuzzy object is visible, which surprises me, since my printed star map (TriAtlas B, with a limiting magnitude of about 12) shows no other objects than the two large galaxies at this area of sky. But as I can clearly make out this bright diffuse spot, I place it on the sketch and can't wait to find out what I really saw. It turns out to be the NGC 7770, another faint galaxy of 13.6m. This value I find a bit misleading, because visually its surface is not this much fainter than its two larger companion galaxies. This discovery makes me really happy, just like when I rediscovered NGC 5981 of the Draco Trio. SQM reading: 20.91 m/arcsec^2.
