NGC 309 - Spiral Galaxy

NGC 309 (Cetus) Galaxy is only just visible in this stacked image due to low S/N. This is a consequence of significant sky background attributed to the Moon (Phase 63%, 29 arc deg offset) .

CCD Image (Linear Scale, 50% size) 5 x 90 sec exposure (average combine), 3x3 binning, C Filter 2014-12-30 21:59hUT (#578170-74) 12" LX200R  (at f/10.4) + ST-10XME
