Description

Just before moonrise: This is a short project of the blue snowball nebula using the big cassegrain telescope of Sternwarte Mirasteilas and long focal length.

The catalog number is NGC 7662, distance from earth is 5000-6000 light years.

This is a planetary nebula with a white dwarf right in the center.

Obviously, it has a very faint halo (IFN/molecular cloud ?) which justifies another imaging session and adding luminance ...
