Description

NGC 2932 - The Eskimo Nebula somwtimes called also Clown Nebula). Its angular size is around 45 '' (arc sec) and brightness is 9,1 mag.

Surrounds the star HD 59088 with 10,5 mag brigthness (surface temperature 40000 K, spectral type O8e). A small difference in the brightness of the star and the nebula makes it difficult to collect material and later with post-processing. Simply - star is overbright the nebula :)
