Balcony?! So Krasnodar is actually Krasnodar itself?
There you have two series in hydrogen. In the series labeled "Krasnodar" - the exposure is increased, and I actually assumed that this was due to the darker sky, and the location label fits as well.

Да прям с города почти с максимальным бортлем. Потому и выдержка побольше. Но это накопление почему-то в копилку дает почти 0. Буду еще Мезмайского накопления добирать и Краснодарское исключать. Хотя оно само по себе свет имеет и по шуму не сильно хуже. Может не так интегрирую. Хз. Пробовал и так и сяк и результат один и тот же.
