Saddle up ! Observing Pegasus.

Shockingly bereft of deep sky objects , especially with its dominance of autumn skies , it does hold some treasures. It’s a useful star hopping square for Andromeda, Aries and Pisces. The brightest star here is Enif , from here it’s an easy hop to the great globular cluster M15. This is only one of two that contain a planetary nebula (Pease 1, +14) , visible with 300mm of aperture.

Some galaxies here NGC 7331 (+9.5) , a very easy target, with a bright core. Better than a log off Messier’s and similar to our galaxy.
NGC 7332 (+10.9), a flattened elliptical, best with 200mm.
NGC 7339 (+11.9), edge on at 200mm.
NGC 7217 (+11.3) and NGC 7814 (+12).
There are two galaxy groups here, “Stephan’s Quintet”,NGC 7317, NGC 7318A and B,NGC 7319 and NGC 7320. This group is east of NGC 7331.
The “Deer Lick Group”, NGC 7331 being the brightest,NGC 7335,NGC 7336,NGC 7337 and NGC 7340. Always worth scanning around these areas , especially under dark skies.

A star by eye is 51 Pegasi , to one side of the square. This was where the first Jupiter like exoplanet 51b ,Bellerophon . This is .05Au and has an orbit of 4.2 days from Enif.

Binary stars.
Kappa Pegasi (SAO 89949). Very delicate at 14.5″at x150.
1 Pegasi (SAO 107073) at 35.9″ , giving an orange and blue couple in small scopes at x50.
Σ2799 (SAO 107165) at 1.9″,yellow twins at x150.
3 Pegasi (SAO 126940) at x50, you’ll get ΟΣ443 in the fov at x50,

Enif, a lovely pale yellow and wide blue ,at 144″.
Σ 2848 (SAO 127196) 10.9″ a grapefruit pair at x50.
Σ2854 (SAO 107633) , challenging 1.7″, split at x150.
Σ2878 at 22h14.5m. +07 59′, a challenging 1.5″ at x200.
Three sets of yellow and blue,
Σ2978 at 23h07.5m. +32 50′ at 8.3″
Σ2986 (SAO 108437) x40 fog this 31.6″ split.
Σ3044 (SAO 108883) at x40 for this 19.8″ split.

It’s a pretty special square for star hopping and guides from autumn into winter , under clear skies !
Nick.
