In depth
A closer look at Siril
Siril Its functionality is based on image-processing algorithms that are fully capable of editing deep sky photographs. This feat is attained through its special feature that detects and registers stars in images. Two main methods, based on Discrete Fourier Transformations and Point Spread Functions, will perform a fully automatic detection process. Manual alignment is also provided, and this means that users who input images of lesser quality, which fail to be corrected automatically, can still salvage them and perform the adjustment themselves.
