      Description

      In an effort to further practice some LRGB processing, and to fill in a few gaps in imaging time while waiting for various targets to rise, I started imaging this beautiful region of space. After having some early success with what I was seeing come through, I made a plan to go for 16 hours of LRGB (4hrs/filter) and my usual set for RGB stars, just to be safe.

      Part way through this, and very much on a whim, I decided to see what kind of Ha response was in this region. To my surprise even single 120s frames had a reasonable Ha signal right in the very bright area, so i decided to throw in 4 hours of Ha while i was at it. Interestingly enough, there is a very small amount of Ha signal present in the dust clouds, and the pressure wave from that big bright star on the mid-right of frame is pretty clearly defined in the Ha. Given the shape, and the amount of blue response around that star, I may look at seeing what kind of OIII signal is there as well.

      As with all my images of late, They're being processed on a Gaming laptop, which has a pretty poorly calibrated screen, so while the colours look pretty good to me, I'm very much open to critique.
