Removing Satellite Trails with Affinity Photo

In this tutorial, Nik shows how to remove the satellite trails which are commonly seen in astronomical images. This valuable technique is an alternative to the common way of removing satellite trails that involves the stacking of several images using pixel rejection techniques, such as sigma-clipping. As sigma-clipping requires at least three frames per filter, this new technique explained by Nik in this tutorial is specifically valuable for One-Click Observations, where you often have only two images per filter.

An extremely useful video and very well demonstrated. It has helped me clean up some serious artifacts!

Thanks David. Glad it was of use. I've since learned that it's not actually necessary to use the 'non-trailed' image as a reference. The Sigma reject algorithm works whichever sub-exposure is used for reference. You never stop learning in this hobby! 🙄
Cheers,
