Sculptor Galaxy (NGC253)

Only 4 of 6 frames were useable - some sort of small guiding or flexure problem happened as I tracked past transit. This was captured on a night of very good seeing at a site with very dark skies to the south - a necessity to capture this object, which was only 18 degrees above the horizon at transit. Although this galaxy is already yellowish because of its high dust content, the image appears to be slightly reddened because of its low altitude. The core was processed to reduce its brightness and reveal more detail.

Verendrye airstrip, September 11, 2010, 1:30 - 3:15 AM; T=+6 to +3 C, seeing very good. 4x15 min, Orion Starshoot on 120mm refractor; no filters; autoguided.
