Hi All,
Here's the Puppis A supernova remnant in Ha/OIII. I used the Ha data for the red channel, and the OIII data for the green and blue, I then combined all the data to make a master luminance frame and combined it all in photoshop.
There is some short RGB data for the stars as well.
A subject with a large dynamic range, some stuff reasonably bright but much more which is quite dim. The blue gradient appear to be real as it is on all the subs. The red nebulosity in the background is one of the Gum nebulae.
A really fascinating target, I hope you like my rendition.

Share and Enjoy.
