donka Posted October 7, 2018 Posted October 7, 2018 There are some stacking options in AP but I would love to see star stacking for astrophotography that would automate star alignment. Is this something that could be implemented? Quote
marcdraco Posted October 9, 2018 Posted October 9, 2018 James Ritson has a rather jolly tutorial on this - although he didn't so much align the stars as take a sequence of high-ISO shots in fairly quick succession so they earth's rotation didn't go an spoil everything. Quote
donka Posted October 9, 2018 Author Posted October 9, 2018 Yes, I’ve seen this video. It’s a good technique but you are limited to how many images you can capture before trails will start to appear once stacked. You are also more or less forced to use a higher ISO to start with introducing extra noise that you are trying to defeat in the first place. It’s all a balancing act I guess but star alignment would be a great addition imho. Quote
Pariah Posted May 28, 2019 Posted May 28, 2019 I'd like to see this too. I do a lot of Astrophotography and have bought Affinity for editing foreground/nightscapes, but would love to see a dedicated star alignment routine for image stacking and de-noise-ing.. Quote
John Rostron Posted May 31, 2019 Posted May 31, 2019 I would see this as an application for scripting rather than macros. You would need to tell the script where the axis of rotation (Pole Star) was then to rotate accordingly. Very often in wider night sky images the background will have more of an effect on the current image alignment algorithms than the stars do.
