I’m new to astrophotography, I don’t have any experience with this, I only use wide-angle lens to take some nightscape photos.
I want stack them to improve Photo quality and keep the meteors. I’m using Linux, so I cannot use PhotoShop and Sequator.
Can I do this with Siril? if it is possible, how can I do it?
Hi, you could keep the meteors by doing a maximum stacking. This will keep the brightest pixels in all images. But this will make star trails too, as Earth rotates. Otherwise, you can do a sum stacking after registering on the stars, but the ground will be turning in that case…
For the landscape part, if you are using a tripod it should be alright, but if there is some movement and the landscape is bright enough, you could try aligning on it with some cross correlation registration methods first.
