Description

To find a previously unknown nebula in such a well-known and often photographed constellation as Cygnus is something very special.
What makes StDr 103 unique is its above-average brightness and its extreme proximity to the famous Tulip Nebula (Sh2-101) of only 42 arc minutes, which makes it a worthwhile target for astrophotographers.

What exactly StDr 103 is is not entirely clear at this time.
The object shows characteristics of a planetary nebula as well as those of a supernova remnant.
Further research on this object will bring certainty in the future.

Many thanks to my teammate Xavier Strottner and of course to Nicolas Outters for this outstanding photo of StDr 103 and to Pascal le Dû for creating a spectrum.
