M101 - Pinwheel in RGBHOO

[mightymonoped]

Had a go at merging the hours worth of HOO data I recently captured together with the 4 Hrs worth of RGB captured a few weeks back.

Created both a finished  RGB and HOO images. The HOO was combined from separate Ha & OIII extracts done in Astro Pixel Processor.

Tried a couple of different techniques but ended up using layer masking to bring in some of the HOO image into the underlying RGB layer, then did some finishing off for the usual stuff.

Nice pic. 
One question if I may: Do you dither between frames?

[mightymonoped]

Yes, every 4 frames.
