This image shows, both some of the strenghts and some of the weaknesses of the Crowd Imaging technique.
M1 is expanding very quickly, and since the images I've used spans several years, the expansion results in motion blur in the final image. I was able to remove some of it using wavelets.
The image is a combination of 109 different images. All processing was done in PixInsight. You can find more information about crowd images in some of the other examples in my gallery.
Even though this resembles NGC 8840, which can be found in my gallery, the two nebulae are quite different ;)
