NGC 7822

NGC 7822

....................................................

This is an emission nebula located in the constellation Cepheus, about 3000 light-years from us, being a region where new stars are born. If the strong radiation emitted by the new stars ionizes the surrounding gas and illuminates the entire area, the same radiation erodes those "pillars" of cosmic dust causing, over time, those concentrated areas of dust to disappear and thus destroy the main "material" that forms the new stars.

Equipment and settings:

Mount: Skywatcher Eq6R

Telescope: Explore Scientific 102ED + 0.75 APM reducer

Camera: ASI 533MM

Filter: Astrodon SHO

Total integration: 10 hours ( Ha 38 exposures x 5 min, Sii 44 x 5 min, Oiii 63 x 3 min )

Edit in Pixinsight.

Location: my Bortle 6+ backyard.
