Description

Experiment with 2" IDAS filter on front of 40mm Nikkor lens.

Over did the exposure although far better than result without filter.

Also having the filter on the front added considerable vignetting which was hard to remove.

Initially stacked in PixInsight with limited success. Tried again using DSS to do the stacking before moving to PI and got a much smoother result with more of the star detail preserved. Probably down to lack of ability on my part rather than PI.
