A small nebula in the SMC.
3.5 hours Ha (red)
3 hours OIII (blue)
synthetic green
Taken using GSO RC10 with focal reducer (f/6.4) on AP900 mount under inner-suburban Brisbane skies. Camera was Starlight Xpress SXVR-H18 with Astrodon 5nm Ha and OIII filters.
I always struggle to get the colour right in LRGB images. Perhaps NB is the answer. Then again, perhaps not
Cheers,
Rick.
