Hi all,
It has been a bit of a journey which included nearly loosing a large chunk of the data with a failed PC.
Some basic info:
-> The image is a blend of 0.55 HA_SNO + 0.1 HA_HNO + 0.35 HA_HSO. I know, not really scientific at all.
-> Integration (203 hours):
HA = 194 x 900s + 157 x 1200s
OIII = 124 x 900s
NII = 88 x 900s
SII = 167 x 900s + 22 x 1200s
-> 4" guidescope, ICX 814, coastal location 20deg South of the Equator.
-> The background looks a bit gritty, but the data is extremely stretched, since background st.dev in all masters was only about 1 ADU.

Thank you for looking
