Description

Had an unexpected few clear nights and wanted to capture the Great Nebula in Carina, NGC 3372.
Its a huge area of HA with strong emissions in SII and OIII.
I tried my best to highlight the three emission lines and how they overlapped and integrated each other shown with the different colour tones.  
This image is cropped as the more I stared at it the more I could see a butterfly...  bringing out my pareidolia here.

I made a combined Luminance image integrated with all three master SHO frames. Stretched each filter with GHS, noise reduction, Imagecombination then added the sharpened luminance image. Photoshop for colour mapping and tone work back to Pixinsight for some curve work.

also big thanks to Adam Block and his website. Great information and support.
