About this object

Name: Pa J0637.4 +3327
Catalog number: PNG 181.2+11.8 
Coordinates: 06 37 28.2 +33 27 07.5 (J2000)

Pa J0637.4 +3327 is a candidate for a planetary nebula in the constellation Auriga and this is the first color image of this nebula ever taken.
The object was discovered by the famous and highly successful amateur astronomer Dana Patchick back in December 2018.  
Pa J0637.4 +3327 consists of a hot star of magnitude 17.19 surrounded by a nebula about 15 arc minutes in diameter. The total extent of the nebula in H-alpha is probably 30 arc minutes or more.
If a spectrum confirms that it is a true planetary nebula, then Pa J0637.4 +3327 is an exceptionally large representative of its class, making it additionally a true rarity.

The image was taken from late October 2022 into mid January 2023. It combines 58hrs and 40min of exposure time through RGB, Ha and OIII filters.
I collaborated with the team of Dana Patchick (Discover), Marcel Dreschler and Xavier Strottner. The image processing and animation was done by Marcel Dreschler and the text explaining the object was provided by him and Xavier Strottner.
