|NGC 4517: Spiral Galaxy (Virgo) RA: 12h 32.8m / DEC: +00° 06'.9|
Instrument: 18-inch Obsession
The long Havana in the sketch at left is NGC 4517. Observed at 199X in the big Obsession, this spiral type galaxy has an integrated magnitude of 10.4. That delicate haze covers a spindly lot of sky, some 10'x1' in dimension. The core region is noticeably thicker and the western 60% of this stellar metropolis glows brighter than the remainder. This signals a more prominent dust lane in the eastern end. Several 12th through 15th magnitude stars frame the view. You'll find this edge-on spiral in central Virgo about 3° northwest of 2.7 magnitude Porrima.
