The Crab Nebula (M1)

This was a bit of an extreme test for this evening's imaging. Using the IDAS dual narrowband filter (NBX) I shot the Crab Nebula (M1) with an Astro Physics 155 refractor.

The Moon was 2-days from full, about 30° from the Crab Nebula, and the sky seemed a bit hazy, probably due to the current Santa Ana wind conditions. The breeze also caused the loss of about 20% of the frames shot. Despite the obstacles, I was glad to not come back empty-handed.
