This time, I calibrated three separate sequences with different exposures, registered them, and stacked them all together. An attempt to capture the Trapezium without a mask.

Photo description / processing
I did some work on fixing mistakes, completely re-shot with a filter and dithering function. I didn't use the cosmicclarity suit. I definitely overexposed the Trapezium, but at least the stars overall don't look like they were just glued on there. It was a moonlit night, too.
