Description

RGB : 10x10x10 x60sec
Ha: 23x300sec
Oiii: 22x300sec

Last night, I decided to go for narrowband after spending some nights on several galaxies despite the full moon.
Few choices at that period so I went for M97 in HOO + 3x10mn in RGB, a little more than the usual 3x5mn for the stars

The faint halo around M97 is barely visible on the Oiii (nothing on Ha) but it is present !
So I decided to try getting at it during processing, this was not easy and perhaps you won't like the "too stretched effect" it gives. It as an interesting processing exercice in my learning curve :-)
