M42 Orion Nebula LRGB

I was hoping to do a bi-colour of this but the UK weather decided otherwise. Got the Ha but I've given up on getting the Olll, so I used the Ha as luminance and added it to my previous RGB efforts. Maybe next winter.....

 

RGB: various scopes and cameras over several years

Ha: 12nm, 12 x 1200 seconds iso 1600

ED80, HEQ5, Cooled mono 450D

Done
