Things did cool down and I managed to get a decent RGB data set of a bit of the Vela Supernova Remnant. I have added the NB data to this RGB.
It is not a final as I am sure I have not got it as good as the information the data contains. My processing skills may/will improve with practice.

The RH200 actually has better resolution with good seeing than the 9 micron pixels of the sensor of the PL16803 camera. With dithering and multiple exposures and stacking upsized this can be recovered. The deep well depth is far more important than going for smaller pixels.
All the data was stacked at X1.5 times the pixel size of the PL16803. This 6000x6000 pixel image shows far better resolution than any single native size image. 20MB

Bert, I'm scratching my head on this one. I don't see how you can achieve better resolution by dithering and simply upscaling your images. It is indeed a bigger image, and dithering eliminates continuous pattern noise as well as other artifacts, but improvement to arcseond per pixel resolution is news to me. Can you explain what you have done in detail?
It would seem like a technique that anyone could apply to their images.
