Crab Nebula Ha/OIII
Here's a work-in-progress. 2.5 hours of Ha and 2 hours of OIII. 15-minute subs - the stars are getting a bit eggy. I've used Ha as the red channel and OIII as the blue, with a synthesized green channel.
I'll try to get some SII, if there is any in this nebula? Also maybe a straight luminosity channel. The detail in this nebula is just fantastic.
This is really my first attempt at narrowband (apart from the de rigour quick try at M42). So any advice much appreciated.
Cheers
Jonathan
