Description

Revisited this target with new techniques, but also to test the efficacy of a light pollution filter, namely the Optolong L-Pro 2". Although this filter is very high-quality and does a lot of the intended things for the process, I decided not to keep it. It didn't remove enough of my gradients, and the amount of reduction that occurred was at the expense of the red and yellow signal strength in the galaxy. For a detailed writeup of this filter, check it out on my site here.

The image contains mixed data, both with and without the filter in place. Not bad overall, but I think I could do similarly well without it.
