About this image

NEW DISCOVERY: Strottner-Drechsler 99 (StDr 99)
We are pleased to present you today the first ever image of a candidate planetary nebula unknown to this day.
Team members Xavier Strottner and Marcel Drechsler discovered this object in June 2020.
This item has been analysed and added to the StDr catalogue by Pascal Le Dû.
StDr 99 is also registered in the PN Global Base managed by Professor Quentin Parker of the University of Hong Kong.
StDr 99 is located in the constellation Cepheus and has an apparent size of 17 arc minutes.
This nebula is so weak, especially [OIII], that nearly 200 hours of exposure were required.
Many thanks to Sven Eklund for working with me in imaging this challenging object, and to Marcel for processing the image.
Data captured between 20 July - 7 August 2022.
