Here is my first ever colour DSO shot with a monochrome camera. I used the un cooled q guider with the 6 inch f3.6 SN as there was high cloud and no good for my usual DSLR shooting, so decided to experiment with the monochrome camera.
I used 30 Baader7Nm Ha images @17 secs each and gain of 55 for red channel
32 Baader narrowband O3 images @20 secs each, gain 55 for green and blue channels (I dont have a SII filter)
30 UV/IR filtered shots 15 secs each gain 58 for Luminance.
Shots aligned then processed with the LRGB setup in Iris. Tweaked in PS
Ive also attached the luminance image I used. Haze and high cloud about.
Guiding manually but using my toucam with Guidemaster, and manually slowing or speeding the drive watching a guidestar on the laptop and occasionally adjusting the dec hand control

Scott, for a 7nm Ha filter you're going to need considerably more exposure time than 17sec! Look forward to seeing some narrowband images from you soon.
Its only going to work on bright subjects. The q guider was never meant for serious DSO imaging. I cannot go past a max of 30 seconds or noise predominates the image. The camera could probably go deeper going full spectrum, that is no filter at all not even a uv/ir one. I did get off a couple of full spectrum frames but cloud came just as I was getting started.
My next plan is to take a full specrum stack and check what magnitude it goes down to. The skies have been terrible here, leading me to experiment with the q guider rather then use the DSLR
