I have prepared a series of images of IC 468 (Thor’s Helmet) that illustrate the benefits of stacking images. Images with total integrations from 10 seconds to 4200 seconds are presented.
I also show images with and without an H-alpha filter. The contrasts are striking. I hope you will take a look and find the page informative.
Clear skies,
