This is a project I've been working on for some time with the Canon EOS Ra.

The final image includes 75 frames (25 x 5-minutes ISO 3200, 50 x 4-minutes ISO 3200).

Total Exposure: 5 Hours, 25 Minutes

I applied a very subtle layer (25%) of my existing Crescent Nebula in HOO (with the Monochrome CCD) on top of this integration for a subtle extra punch in OIII.

I hope you like it!!
