Photo description / processing

I started shooting the crescent and an idea came to mind — why not make a mosaic. I aimed, one might say, by eye using a photo from my phone; the rotation angle was the same, so I didn't miss by much. This was my first experience assembling a mosaic, and I didn't immediately understand how to do it properly in Siril. It took an hour to get the hang of it, and everything aligned and then merged correctly by layers. Of course, I cropped the frame quite a bit, but I gained invaluable experience and want to repeat it more deliberately. I kept the balance by having the same number of frames in each panel; I just didn't manage to capture the crescent.

We need to be friends) otherwise I shoot the surroundings of the star Sadr at 135 mm and also had the thought, what if I make a mosaic of Cygnus with the Samyang and 533 MC Pro, I have two panels Sadr-Crescent and Sadr-Tulip, so I want to do the stitching, I don't know how yet, I haven't even raised this question yet.

Yesterday I shot roughly the same frame, but there the Tulip is even farther away)

In Siril there's nothing complicated. You just need to load a bunch of already calibrated frames into one sequence, and apply the astrometric solution to the whole sequence before registration. Then in the registration window select maximum overlap and it will assemble the mosaic image itself. With the 533 it should work well. The main thing is calibration and that the background is even everywhere without clouds over half the frame.
