Sharing a very modest 3 hours of integration time on NGC 1909 Witch Head Nebula.

Great job!

I am marveling at the result of a small amount of data, a sensitive hi res cmos osc camera, and relatively little processing effort (maybe an hour or so?) thanks to modern software and techniques.

I agree 100%. The modern CMOS cameras are wonderful!

Here's my Witch Head from 2019: <http://astronomy.mdodd.com/nebulae-23.html>

My small FOV required a 2-panel mosaic that excludes Rigel. Like you, integration times were relatively short -- only 2.5 hours per panel. Maybe I'll go back for some more data with the coming new Moon.
