Description

The actual exposures were:

Ha 12 x 1200s and 7 x 1800s

Red 3 x 600s and 21 x 120s

Green 18 x 120s

Blue 2 x 120s

Yes that is just two 120s subs with the blue filter, and I am very pleased how well this image turned out. I was planning to address that with more blue & green subs, plus more Ha to go deeper and also some OIII, but perhaps I won't, as a re-process using the existing data improved the image enough so I now declare it finished.
