I’ve been tinkering with full narrowband on and off for ages, but never managed to get anything resembling an image. I don’t know if it’s just now that I’ve moved to a 100mm scope, but things seem to be falling into place now.

So here is my first ever full narrowband image, to say I’m chuffed with this would be an understatement. There’s still a lot of bits to figure out mind you, like purple haloing and the purple sky background. I might add another hour each to OIII and SII to see if I can get it a bit smoother. I had to download a trial of Photoshop CS5 to tweak the colour as I couldn’t find a way to do it in PixInsight, so it might be worth buying just for final tweaking. I’ve added the Hα only in as well.
