Added almost an hour of hydrogen sulfide during "nautical twilight" with a full Moon.
The goal was to test exactly this equipment setup.
The test was partially successful - in the middle of the session, there was an autofocus failure and a significant portion of the material went to the trash. On the remaining data, both sulfur and hydrogen-beta are visible, despite not the most favorable shooting conditions.

Добавил почти час сероводорода в "навигационных сумерках" при полной Луне. Задачей был тест именно такого набора оборудования. Тест частично удачный - посреди сессии был сбой автофоку...

Первый свет приехавшей трубы с полеспрямителем. Хоть и дублет, хроматизма прям явного не вижу. Пойдёт под бочёк Askar 103 APO второй трубой, она с редуктором 0,8 то-же фокусное 560мм имеет. Темн...

I'm also considering this telescope. On Cloudynights, they mentioned that the 80ED produces oddly shaped halos around bright stars in the corners. Have you experienced this?
