Notes: This image is one of the first of this December (2007) that highlights the poor seeing of this entire month ... had a lot of off-shore winds (Santa Ana's) that made focusing difficult. Also, this image is not well captured by the Deep Sky filter ... would probably have been better with the red filter (or a narrowband Ha). The large field of nebulosity to the west (right) is the edge of IC 1848, a large (100' x 53') bright nebula also known as the "Soul Nebula". See this wonderful color image by Dr. Walter Koprolin that show the relative positions of IC 1871 and IC 1848.
