Image:

Lumicon Red filter, 1000 minutes (100 x 10 minute subs), 11/22/23/25/27/2015; seeing 2.3-4.5 FWHM per CCDStack

Location:

 Rolling Roof Observatory, Thousand Oaks, CA 91360 (+34d 13m 29s -118h 52m 20s)

Notes:

Another frustrating image this November ... the poor placement relative to the full moon made terrible gradients. The seeing was mostly poor (most subs in the 3.9 to 4.5 range), as the the 2.3 arc sec was really only one out of 108 subs taken.

Berkeley 9 is to the northeast (upper left), and Czernik 16 is just west (right) of the center. See the 8" version.

According to "Star Clusters", by Brent Archinal and Steven Hynes, the size of Berkeley 9 is 4.0 arc minutes, and the size of Czernik 16 is 5.0 arc minutes
