Slightly brightened the existing photo, didn't redo anything. I've been looking at it for a long time, wanted to for a long time, but didn't want to spam. The periphery remained as it was, just became more noticeable.
Немного осветлил имеющееся фото, ничего не переделывал. Давно смотрел, давно хотел, но не хотел флудить. Периферия осталась как и была, просто стала более заметна.
Good day, Evgeny!
Great work!
I also have a ZWO 294 MM.
I have a couple of questions:
For bin 1 and bin 2 modes, do you need to shoot different darks?
What is the reasoning behind using zero gain?
Hello! Yes, dark frames are captured exactly matching the lights, bin2 is not equal to bin1. Zero gain was part of an experiment; I observed different objects, thinking that with long exposures the signal would be cleaner, or rather, the noise wouldn't be as amplified. Currently, I'm shooting more with short exposures at 120 gain.
