Constellation - Serpens
Open cluster and emission nebula
Distance - 9000 Ly

Antoniadi III

Sketch notes
Went in search of M16 without a filter, found the open cluster easily but hardly any trace of nebulosity. A UHC filter greatly improved the view but I'm pretty sure a OIII filter is better suited.
Quite dim at first but after a while the outline became alot more apparent.
