NEW DISCOVERY: StDr 140 – Lori’s Nebula in Gemini

A new discovery of a candidate planetary nebula in the constellation Gemini. The object was discovered by my good friends the German-French team of Marcel Drechsler and Xavier Strottner in October 2021 using digital sky surveys. This is their 140th joint discovery. Currently, only very few planetary nebulae are known in the Gemini constellation, and now this impressive new nebula has been added. Because the PN candidate is rich in ionised oxygen (OIII), the object appears in a ghostly turquoise blue. It is at an estimated 4,250 light years from Earth.
My thanks to Marcel Drechsler for so expertly processing this image.
