Image:

Lumicon Red filter, 550 minutes (55 x 10 minute subs), 04/26/27/28/29/2015; seeing 2.5-5.0 FWHM per CCDStack

Location:

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

Notes: Playing 'keep away' from the moon again, as it is invading the galaxy filled southern skies ... rather poor seeing for a lot of the subs, as the bouts of high clouds were accompanied by mild off-shore winds.

IC 1251 (1.4'x0.9', mag 14.2p, Cl: Scd:) is north (above), and IC 1254 (1.5'x0.6', mag 15.0b, Cl: Sb? pec) is northeast (above left).
