Vela SNR in 3nm NII and OIII blended with RGB

Compared to facing the threat of bushfires, 40C days and 30C nights are really only a minor annoyance. When temperature controlled optics are hotter than their set temperature trying to collect any data is a waste of time.

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
