The weather forecasts are conflicting. The sky just won't let me gather more data! I have to push the gain up. Even here, it's only about an hour's worth, but still, thanks for letting me see what I wanted!)) Soon, I'll probably start collecting data on one object over several days, or even months! We'll see)

Проверял на своей asi533 gain 100 и 300, в итоге при растягивании одно и тоже получается. Но при увеличении gain, динамический диапазон падает. Думаю на ASI294 тоже инвариантное усиление и нет смысла увеличивать больше рекомендуемого 120.
