NGC 6888 - 8.11.2021 at 00.00 Nakkila Observation number 102114

Visibility IV / V

Tomi Kurri, Porin Karhunvartijat

My autumn observation project has been the Sickle Nebula in the constellation Joutsenen. There is a lot of opaque hydrogen mist around the site, which is aided by rapid optics.

The total exposure time of the image is almost 10 hours. The camera is a ZWO 183MC Pro color camera.

      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.
