NGC 2857 or ARP 001, spiral galaxy type Sc, along with ARP 285 to the lower right, which is comprised
of NGC 2856 (spiral galaxy type Sbc) and NGC 2854 (spiral galaxy type type SBb) in Ursa Major. The
accretion tail perpendicular to NGC 2856 is also faintly visible. Taken in average to poor seeing
and transparency on March 12, 13, 19, 23, 24 and Mar 27 2009 with CCD Lab’s Q285M and a C8N at f5 on
a Losmandy G11/Gemini mount. All subframes were 5 minutes binned 1x1 resulting in the following
total exposures L:R:G:B (min) = 305:75:75:75. Captured with Nebulosity, calibrated and sigma
combined in Iris with other processing using PixInsight LE and Photoshop CS. North is up.
