Description

I composed this image with shots over the course of four nights through September and October 2017. Processing was much easier and less noisy with just over four hours of integration time and 82 light frames. From now on I will aim for four hours minimum.

This was also my first time auto-guiding my setup. This enabled me to take 180" lights where as before I was limited to 120". I'm still working on perfecting the guiding, I discarded 25% of the frames due to trailing or oblong shaped stars.

I used PixInsight for the stacking and processing. I followed Jon Rista's method for noise reduction and Warren Keller's Inside PixInsight workflow along with Kayron Mercieca's tutorials on Light Vortex Astronomy.

Aquired:

107x180"

Stacked:

Integration: 4.10 hours
