2nd image using the Optolong filter. The subs were so free of light pollution from the new filter, I stacked and edited only in Photoshop to see how it would look. Compared to my earlier version, the stars are tiny and non-distracting and let other detail reveal itself as well. Also, I just have not had this sort of detail in my images with so few subs, so for me, the filter has exceeded my expectations.
