Description

Ingrid's Nebula is a new candidate of a planetary nebula in the constellation Serpens.
It was discovered by the German-French team of Marcel Drechsler and Xavier Strottner in 2021 and has the catalogue designation StDr 153 / PNG 014.6+00.7.

This photo, taken in collaboration with my friends and colleagues Peter Goodhew from the UK and Marcel Drechsler from Germany, is the first one ever taken of this faint object. The name "Ingrid´s Nebula" is a tribute to my mother, Ingrid Eklund.

Typical for planetary nebulae is a compact envelope of H-alpha and OIII surrounding a tiny white dwarf.
The central star is exceptionally blue, suggesting a temperature of 30000K or more.
An exact distance determination was not possible due to insufficient GAIA and TESS data.

At the moment, a spectrum (a chemical fingerprint) is in progress, which will hopefully confirm that Ingrid's Nebula is a true planetary nebula.
