M42 narrowband colour

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
