Description

Faint - fainter - Strottner-Drechsler 99

Strottner-Drechsler 99 is a probable planetary nebula in the constellation Cepheus.
StDr 99 was discovered by Marcel Drechsler and Xavier Strottner in 2020 and photographed for the first time by Peter Goodhew and Sven Eklund in 2022.
The PN candidate is so faint that almost 200 hours of exposure time were needed to make the entire shell visible.
The OIII component of StDr 99 is so faint that it is close to the detection limit.

This makes StDr 99 one of the most difficult objects ever photographed by our team.
