Here is my latest portrait of the Vela Supernova remnant. I have mapped the Hydrogen alpha data to red and the OIII data to teal. One version includes the RGB stars at the expense of detail in the nebulosity. For the other version, the stars were removed using Starnet ++ to emphasise the intricate tendrils of the Oxygen nebulosity. I think I prefer the version with no stars because of intricate detail revealed. I know some of you consider star removal a tedious fad, but it does reveal more detail in the nebulosity. Please feel free to offer a different opinion.

Higher (though not full) resolution versions are here:

Murray that's magnificent, and one of your very best. :thumbsup::thumbsup::thumbsup:

Tell me it's not a pair of happy horse-cattle hybrids trotting toward us! Totally convincing, right down to the eye lashes.

Wow, amazing. It took me a while for my mind's eye to "click", but I see it now. Two cows, the resemblance is striking.

That's a wonderful image Murray. I love a good Vela image and this one is superb.

A really wonderful rendition. The hours put into image capture have brought out the tendrils beautifully

Very cool Murray. Lot of work going into that and it shows. Not usually a fan of starless but I really like this. One for the poolroom. :thumbsup::thumbsup::thumbsup:
PS: I cannot unsee the cows now either. :lol: Print it and get it framed.
