About this image

This is my first go at aligning and blending two stacks, first shot early September with my DSLR and second with new ZWO 2600 using optolong l-enhance in an attempt to limit the moonlight. Aligning and blending the stacks in Affinity photo turned out to be very easy. The narrowband shots bring out the spiral arms and WR stars pretty well.
