Anchored by the galaxy pair NGC 7626 and NGC 7619, the Pegasus I group straddles the border between Pegasus and Pisces. POSS-II / STSCI / CALTECH / PALOMAR OBSERVATORY The Pegasus I Group Straddling the Pegasus-Pisces border, the galaxy grouping dominated by NGC 7619 and NGC 7626 is sometimes called the Pegasus I group.

Such a sky is described as transitional between rural and suburban environments with a naked-eye limiting magnitude between 6.1 and 6.5. On this scale, a 1 is easy and a 7 probably isn't visible. The estimate is meant to offer a relative assessment of difficulty, but don't let it discourage you from trying even the most difficult objects. The only true assessment of difficulty will come from your own best attempt at detection. The magnifications listed are a recommended starting point. You will benefit, of course, from varying your magnification to suit your own circumstances. 8 9 10 11 12 13 7611 +8° 00′ HD 219949 Sk yandTelescope.com October 2015 33http://www.SkyandTelescope.com
