Description

Strottner-Drechsler 140 / Lori's Nebula is a candidate for previously unknown planetary nebula in the constellation Gemini. The object was discovered by the German-French team of Marcel Drechsler and Xavier Strottner in October 2021 using digital sky surveys. Currently, only very few planetary nebulae are known in the Gemini constellation, and now an impressive new nebula has been added.
I finally offered the team to shoot the new PN candidate with my two APM Telescopes APO refractors in Extramadura, Spain. 76 hours of exposure time were needed to image this extremely faint, bubble-shaped PN candidate in all it's details. Because the PN candidate is rich in ionised oxygen (OIII), the object appears in a ghostly turquoise blue. You can see the exciting result here.
