Astrophotography HSO Narrwoband

[Dan_Valentin]

Hi !

When I started to use Affinity Photo I was looking at some tutorials on youtube related to HSO narroband image stacking. If I remember correctly, it was James the product expert that upload the tutorials. For some reason I can't find them anymore. Could you please tell me whether they can be found on Affinity's website, or this blog ?

 

thanks in advance

Hi @Dan_Valentin, I know which ones you're referring to, they still exist but are unlisted on YouTube and can be found on the V1 tutorials playlist: https://youtube.com/playlist?list=PLjZ7Y0kROWitoJtnw0pdvjPmS8mYGvrBR

They're not organised however so that could take some time to sift through. I do still have them linked on my tutorials page: https://jamesritson.co.uk/tutorials.html

Please be aware however that they're a little outdated: the stacking process with bad pixel map generation is a bit needlessly complex, and the default stacking settings have changed for V2 which can make this part unnecessary for a majority of data. You are better off stacking with sigma clipping and lowering the default clipping value of 2 before trying to manually alter the bad pixel map.

Hope that helps!
