Why you should reprocess old data - I reprocessed my Rosette Nebula from last year

What do astrophotographers do when it's cloudy? They look back at their old data and see if they can improve upon it. In this video I do just that. I take my Rosette Nebula data from January 2021 and reprocess it using the techniques I've learnt this year.
Previously I processed this using photoshop and I ended up with big stars, grain etc. but with PixInsight I ended with an image I am much happier with.
