Last September, in my first outing with a new-to-me Nikon D5300, I collected 96 minutes of the Wizard Nebula via my AT130EDT from a dark site.
Back then I processed the image using my then-normal workflow and I was never satisfied with the results. The Wizard Nebula is faint, especially for a non-modified DSLR, and it sits in the middle of the Milky Way, so it is overwhelmed by the stars all around it. I made several attempts by using Morphological Transformation in PixInsight to reduce the “importance" of the stars, but I would get unpleasing star artifacts and, in general, a washed-out appearance, like here:
In these past few months, however, I have learned a few new tricks in PixInsight, among which the use of the Arcsinh stretch, and Adam Block’s technique for star de-emphasis (see https://youtu.be/SPFsoO0ZWeg?t=3679). Today I re-processed the same data set using those new methods, and I was blown away by the improvement:
What do you think? Comments are very very welcome.
