Astrophotography
This is the first time I've tried something like this. I wanted to see how far I could push my phone with manual astrophotography. Honestly, I didn't expect the sensor to pick up this much detail from the Milky Way core.
I processed the whole stacking and stretching workflow in Siril. For post-processing I used Photoshop.
The process is explained by @Ornery-Art-7696 in his/her milky way post: https://www.reddit.com/r/S24FE/s/kt8gzN919T
Aside from this post, I also tinkered with the program myself and learned how to use it. Currently, I don't have a set of ready-made, "rule of thumbs" settings. I achieved these results through trial and error, playing around with the parameters. The camera pro settings I used were as follows:
ISO: 800-1600 (I adjusted this according to ambient light intensity) - The Bortle scale at the location where I took the photos was around 4.2-4.6
Exposure: 15 seconds
Focus: MF - Regarding focus, you need to identify a star in the sky, point the camera at it, zoom in all the way, and then adjust the MF value accordingly. If you increase the MF value too much, the star will spread out over a wide area like a disk. We don't want that. Instead, the MF is correctly set when the star is sharply defined like a point.
Temperature: 5200K
I also processed the photo by dark frames. I tried flat and bias frames, but I didn't use them because they caused image distortion (maybe I just didn't make it work). Apart from that, I consulted Gemini a lot to advance the process. I asked it in detail how to take dark frames, etc.
I was able to find all the information about the general usage logic, operation, and problems I encountered with the Siril by searching online.
I wish good luck to those who want to take photos. I can also help with any questions you may have.
