Description

Very humid night and bad tracking on this one, most of the clouds seemed to like the OIII moments and so got little usable subs with that filter. Also the usual strong and clear Ha part was very noisy.

Nevertheless a pretty interesting subject that deserves better subs and a clearer evening!

Color combination is based on SHO with 80% of the main filter and 10% each of the other two, with strong SCNR to remove the green bias.

Using the Ha as a Lum didn't really help compared to other images I've done in the past, just the stars got smaller and sharper but the nebula was actually losing detail, so not worth doing it.
