About this object

Sh2-290, also cataloged as Abel 31 and PK 219+31.1 is a dim and large planetary nebula in the constellation Cancer. Its a Planetary Nebula and is the remnant of a star that has blown off its shell of gas into space at the end of its life. The bluish green interior is due to ionized oxygen atoms and the reddish outer shell is the glow of hydrogen gas. This image was taken from my suburban backyard with my 10"/ 250cm astrograph. Red, Green, Blue, Hydrogen and Oxygen III filters were used. This is a reprocessed version of the original data taken in 2013. The original processed version is here: Sh2-290
