Description

This is perhaps one of the most popular targets in the night sky. I never imagined to photograph it as it is so big for my old scope (1470mm).

It is now a perfect match for my new setup and naturally becomes my first light object to shoot. I did the Ha from home for 3 nights and then drove to HAS to complete the LRGB part. It was expected to last 3.5 hours in total according to the acquisition sequence but some thin clouds blocked the view as soon as B was done. I had to take more reds than I had planned for and thought it could have been pretty bad. Luckily the normalization process averaged out the impact and I'm pretty happy with the result.
