discovered or rather catalogued for the first time in the 18th century by the astronomer Charles Messier, also known by the names “Dumbbell Nebula”, “Diablo Nebula”, is a fantastic planetary nebula with very bright emission, visible in the direction of the constellation of Vulpecula, about 1200 light years from the Earth and with a size of about 2.5 light years. Its formation is due to the death of a star similar to our Sun, which exhausted its energy in its nucleus and expelled its outer layers into space, with its visible glow generated by the excitation of atoms illuminated by ultraviolet light.
For the composition of the final image, I used the HDR technique of Pixinsight, with the sum of 10” lights and 300” lights, in order to be able to average the exposure dedicated to the nucleus and stars and make them not excessively saturated.
Telescopio: Celestron EdgeHD 11”
Camera: ZWO ASI183MC Pro
Montatura: Sky-Watcher EQ6-R Pro
Filtro: Antlia ALP-T Dual Band 5nm 2”
Accessori: HyperStar 11 v4 (HS4-C11). Date: 06-07-08 Agosto 2024
Fotogrammi: 264×10,″(44′) 199×300,″(16h 35′)
