Nice one! Do you recall your sub exposure times for that shot?

I'd get as narrow as you can afford, it will have better light rejection and contrast.

Good advice, your M8 shot is awesome, what length of subs were they on the mono camera? cheers

Cool, that's a lot of detail from 12nm Ha, you should be happy with that

if I understand this correctly, you stack and process the Ha and RGB subs separately, then use the red channel from the ha image when merging the RGB image in PS.

Thanks for your input folks, does anyone have examples of HaRGB merged images from their OSC or DSLR to show?

Cheers
