How to use the stacking method to reduce noise in astrophotography


I have been fortunate enough to witness some aurora displays so bright that the very ground beneath my feet was light bright as if a full Moon was out. 

But most astro phenomena are much fainter. Few more so than a 1.2 km comet nearly 40,000,000 miles away! So, how can you maximise your chances of picking up an object so elusive that the human eye can't even pick it up?

In this eBook, I use the case study of comet 21P to teach you how the stacking method can help control noise in your low light images. Along the way, you'll learn more about comets, where they're from, and how they link to that most magical of astro features - meteors.
