Good day, could you explain what determines the resolution and file size of the final image? Why do some images have a resolution of, for example, 5000×2700, while others are 1900×850, and the file size of the first is around 10 MB, while the second is only 900 KB?

Hmm... You can crop the frame, resize it during processing. And different formats.

When shooting with the ZWO ASI 294 MM Pro in bin 1 mode, the sensor resolution is 8288×5644 (46.8 megapixels). Accordingly, in bin 2 mode, the sensor resolution is 4144×2822 (11.7 megapixels). Simply put, the weight of the photo primarily depends on the physical pixel size of the sensor and the sensor size in millimeters.
