Description

Revisiting an old favourite object, but with better equipment and 4 years more experience than last time ;-)

A first attempt at combining RGB stars with narrowband data. Have to say the OIII is very weak here, I struggled to get much out of the 9 hours of it that I had.

Ha - 20 x 1200s

OIII - 18 x 1800s

RGB - 6 x 600s each (star colour only)

All subs binned 2x2
