I have finally tweaked the ITS (Image Train Stabiliser) to give me almost perfect orthogonal alignment of the camera with the optic axis of the RH200. This will be a thread on its own.
Collected 10 X8 minutes each of SII, NII and OIII. These were mapped to RGB, SII to red, NII to green and OIII to blue. The Moon was at about 90%.

I am sure I could do better but it is my first attempt at colour NB.
If enough people are interested I can put up the 16 bit data in fit or tiff to have a play with.
Best Christmas present in years. Got the image train aligned and two clear nights in a row!
