Hi Peter,
Your pic is already one of the best I've ever seen.
To halve the noise - which is so small now -
you'll need too much more data:
SII = 8 frames now = 1/√8 = 1/2.82 of noise follows half noise again = (2 * 2.82)² = 31 follows that
31 - 8 = 23 extra frames = 690 minutes = 11.5 hours extra hours.
Ha = 15 frames now = 1/√15 = 3.87 (2 * 3.87)² = 60 frames
60 - 15 = 45 extra frames = 45 * 30 minutes = 1350 = 22.5 extra hours.
OIII =25 frames now 1/√25 = 5 ( 2* 5)² = 100
100 - 25 = 75 extra frames = 75 * 30 minutes = 2250 = 37.5 extra hours.
That equals a total of a further
71.5 hours to halve the noise in each channel!
Isn't 24 hours of data enough?
These are the days of mega data.
cheers
