IC 1795 - 25.11.2017 at 19.00 - 26.11.2017 at 05.30 Kankaanpää Observation number 69518

Visibility Unclassified

Tero Hirvikoski, Ursa (Länsi-Suomi)

The object in the picture is part of a larger nebula complex known as Heart Nebula in the constellation Cassiopeia. The filming dates were November 25, 2017 and December 21-22, 2017. Even less exposure would have been sufficient for the main subject itself, but a total exposure time of ten hours made processing easier and exposed the dimmer mist to the environment.

      In an emission nebula the hot stars nearby cause the gas glow. This should not mix with reflection nebula, where the gas is only lit up by nearby stars.

      The appearance of a gas nebula is irregular, and the fainter parts of it need bigger instruments to be visible.

Silmä lepää tässä kuvassa, tekniikka hallussa ja hyvin käsitelty.
