ngc6302 Ha now with colour added + super-res stack

Used some fairly low quality RGB data to add colour to an earlier posted Ha image. Blending Ha with the noisy low res R was not an option, so the Ha was used directly as the luminance - this skews the colours a bit (particularly the star field), but the addition of colour of any sort seems to have brought out some structural features that were not as obvious in the Ha, so it seems to be worth having. And it looks more dramatic - that must have been some explosion.

Thanks for looking. Any ideas on how to better combine hi res Ha + low res RGB gratefully accepted. Regards ray

Edit: added a manual sort+super-res stack of the Ha data - gained a tiny bit more detail.
