Next time you’re going to take a sky photo, don’t take one, take at least 20. Between shots, put the lens cap and shoot. You’ll have a darkframe. Take a couple of darks during your session, say 8 for the 20 photo session? 15 for a 50 photo session? There’s an ideal number of darks, but I don’t have the reference now. I think better have some than nothing.
That is the most important part.
Then, when you’re up to, you follow that tutorial.
By the way, nice image! I liked the framing very much!
I was able to run it in Mac using an emulator (I think it was Wine), but you are right, it is not native on Mac. You can use Starry Landscape Stacker on Mac. It does the same and you can find it in the App Store.
I used it a few times, some years ago, and it’s good.
Basically Siril, but with a bit more functionality. As I recall, in the alignment part: you can choose if you want to align stars or planets.
I had a very good impression from it, and it was the only one that allowed me to stack images with very few stars at the time.
Well, but I’m completely amateur on this, so, caution with my words.
Sebastien, thanks for this excellent tutorial. I’ve downloaded Siril and your example images. What lens and aperture did you use? I’d like to play around in Darktable and use corrected tiff files instead of RAW files to see if that changes anything. Thanks.
Thanks! Regarding the lens and aperture used, I don’t have the files at hand, but you should see that in the exif data. If you see “12mm f/0” then it’s a Samyang 12mm f/2. Otherwise it should a Fujiflm XF 23mm f/1.4.
I’ll give more detail when I can check the files.
Thanks. I’m just amazed by how many stars can be pulled out by stacking, given such a short exposure of only 10s! And the reduction in noise is fantastic.
