About this image

Here is one for Haloween.

It had to be narrowband only with the almost full Moon. Captured over two consecutive nights; the first clear sky for a long time.

Processing in Pixinsight and Affinity Photo. The tone mapping function in Affinity is superb at bringing out the fainter details in any nebula or galaxy.
