M81 - lots of R and the rest not so much!


Recommended Posts

This is a combination of several partial sessions that I had to stop for one reason or another. 10hrs split as 4hrs of R, 2 hrs of G and Ha, and only 1hr of B! I've no idea how many frames were rejected - I left that to the WBB scripts. I plan one more session for L, B and G and hopefully I can reduce some of the chroma noise. I think I see red breaking through like a crackle glaze. Reading Jon Rista's advice, he suggests <> 400 subs per channel for a low noise image (3+hrs per channel)


I'd like to make the Holmberg IX dwarf galaxy a bit more prominent too if I can (I have some Ha there but it's very faint).
