Orion Nebula practice files (original FIT data and edited Affinity Photo document)

This is a set of practice files for stacked deep sky astrophotography post-processing.

Included is the source data for stacking in calibrated FIT format. This particular data was gathered with a monochrome camera setup, so the stacking process involves stacking each data set and then creating a bi-colour HOO composition.

An Affinity Photo document file is also included, so you can fully explore the non-destructive layer stack—you can hide, show and manipulate layers and see how they all contribute to the final result.

Many of the non-destructive techniques used are as a result of my Astrophotography Macros for Affinity Photo. You can download them for free from my website: https://jamesritson.co.uk/resources.html
