StDr 138 is extremely faint and has a distance of about 3100 lightyears to Earth.
It is located in the constellation Perseus and has a size of 13 x 9.5 arcminutes.
This probable bipolar planetary nebula was discovered by the two amateur
astronomers Marcel Drechsler and Xavier Strottner in 2020.
This photo is the first ever taken of this probable PN.
