    NGC 7331, 7479, 7814, and again M74 with sn2013ej

    Last night I observed from our rural club site. A 45-min drive and got 21.2 mag/sq arcsec in the culminating Pegasus and Pisces. But the familiar galaxies lacked a lot of punch as well as some actual detail compared with my favorite remote site 3 hrs away (typically 21.7 mag/sq arcsec). Be that as it may, here they are as seen mostly at 225x with 16":

    Nice to compare! I see you glimpsed the equatorial dust lane in NGC 7814. Does it require good seeing as well as good thermal equilibration of the 16" f/4.5 mirror, or is it a relatively robust feature in your experience? What magnification showed it best?

    Hi Ivan

    With 240x I saw the equatorial dust lane directly. The seeing was very good! 520x was no problem and sharp!!I observed at 1100m in the Alps.
