Description

NGC 6905 also known as the Blue Flash Nebula, is a planetary nebula in the constellation Delphinus. It is very small: its internal shell has angular dimensions 47"×34” and roughly conical extensions, with ansae-type formations along the major axis.
The central star is a white dwarf with an estimated surface temperature of 150.000 K.
The distance of the nebula, as with most planetary nebulae, is not well determined and estimates range between 1.7 and 2.6 kpc. (Text adapted from Wikipedia)
