Affinity Photo just dropped a huge update to their software line-up adding a tonne of features that are well worth checking out. However the one that caught my eye was their new AstroPhotography Stacker which is a one-stop-shop for stacking all your lights, darks, flats, dark-flats, and bias frames into a final stacked image ready for further processing; not even photoshop has such a function!
The video covers all the functions and you do get a nice result out of the process. There is a lot of automatic functions running in the background to get you to that stacked image which you don’t have a huge amount of control over (like you would if you were doing this manually or using PixInsight tools) but the trade off is the learning curve is dead simple and the results are more than acceptably pleasing.
I’m not as familiar with Affinity Photo (I just downloaded the Trail version to give this new feature a try) but you can see from the comparison below that it does have all the tools you need to adjust your photo after you finish the stack.
