NGC 7137 (Galaxy) Right ascension: 21h 49m Declination: 22° 14' Constellation: Pegasus Date/time: 2016.08.03 23:15 UT Equipment: 12" f/5 Newtonian FoV: 16' Magnification and filter(s): 250x Seeing: 7/10 Transparency: 5/5 SQM: 21.55 m/as2 Temperature: 16°C Humidity: low Wind: none Sight: 2 - minor details, somewhat interesting Difficulty: 3 - moderately visible, dark adaptation needed, averted vision might add to details Position: 3 - moderate, some starhopping needed Location: Talpa Minor Observatory Observer: Ferenc Lovró Description: Surprisingly easy to see, as a tiny, fuzzy little spot. Slightly elongated to the W-E direction, but it's almost disk-shaped. It displays a very sharp edge which makes the looks spectacular. This edge is best visible with averted vision. Completely homogeneous. Hi-resolution image: [ reversed sketch | original sketch ]
