M33 - Combined RGBHaOiii

[mightymonoped]

Managed to grab just over an hours worth of usable frames (the rest destroyed by high cloud), so I though I’d have a go at merging it with last years RGBHaOiii capture. 
 

Having tried various integrations, I decided to treat the two images as distinct, then register them against each other before merging them. 
 

In the end, I used the starless version of the RGBHaOiii capture and merged it at 50% with the ‘starry’ recent capture. 
 

Both images were processed using Astro Pixel Processor, Pixinsight (and the RC suite) and Photoshop to combine. 
 

All captured using Skywatcher 80ED (gold)

ASI294mc pro -10c unity gain.
