Description

In November the helix nebula was hidden soon. I needed 13 sessions to acquire an exposure of more than 11 hours. I added little OIII component to the final image, because I think that an excess of OIII made the image less beautiful.

R: (21 X 6’) +( 8 X 4’) =158’

G: 20 X 6’ = 120’

B: 21 X 6’ = 126’

OIII: 24 X 10’ = 240’

L: 15 X 4’ = 60’

TOTAL: 704’ = 11 h 44 min
