|Palomar 11: Globular Star Cluster (Aquila) RA: 19h 45.2m / DEC: -08° 00'.5|
Instrument: 18-inch Obsession
Palomar 11 is presented in the sketch at left. My drawing records a 141X view in the 18-inch Obsession. The globular star cluster emerges from the late summer sky under direct vision, a 7' diameter patch of light. Its estimated brightness is 9.8 magnitude. Several brighter members are visible and these give Palomar 11 a salty or slightly grainy appearance. The typical cluster member shines in the mid-16th magnitude range. I wonder what Palomar 11 looks like in a 25-inch or larger instrument. In my drawing, 8.6 magnitude HD 186496 stands sentry along the northwest edge of the cluster. Another 60-odd stars dot the field. You'll find this patch of sky in southern Aquila about 11° east-southeast of 12 Aquilae.
