Before the end of the year I want to share with you this image of IC 1848, also known as the Soul Nebula in Cassiopeia. I took this image in RGB with the IDAS D1 filter in RGB and the Baader Ha 7nm filter to enhance the nebula in the red channel.
Total exposure was 5hr 16 min at f2.3 with a modified Canon T1i on a hyperstar lens and a C925 EdgeHD. Of that time, 2 hr 25 min (29 x 5 min) at ISO 1600 were for Ha, and 1 hr 51 min (57 x 3 min) at ISO 800 for the RGB image. Mount is an iOptron CEM60.
Captured in SGP and completelly processed with Pixinsight.
