Pa 157 spectrum

Post by Pascal Le Du »

Hello

Black sky periods are currently short and it is not easy to shoot low-light objects
I was able to capture the spectrum of a possible planetray nebula from the Deep Sky Hunter list : Pa 157 (Dana Patchick's discovery).
One hour to acquire the spectrum of this object, obviously invisible on the autoguiding sensor.
We can see the [OIII] and Halpha lines. Certainly a true PN.
