Incredibly easy to shoot, incredibly hard to process.
Brightness distribution across the three standard narrowband channels makes getting some clear transitions in colour surprisingly challenging with this target.
Made 8-10 different colour blends with this one before I landed on something I quite liked; and about the same number of iterations on the luminance blend trying to get the bright parts to blend in with the fainter background dark bits less aggressively.
Very tough not to end up with a completely 'neon' looking combined image. Anyway, hope you like the balance I've tried to strike.
The 2600 coupled with a 3nm filter rips some amazingly low noise and high detail Ha data, very impressed.
my own flavour of foraxx sho with rgb stars.
