Description

This is Purgathofer-Weinberger 1. It is very diffuse, faint, large and nearby planetary nebula in the constellation Lynx. It was discovered in 1980.
Took me a whole season to image this very faint object. 
The 1st rig was:  G11,RC10, CCDT67,IMX571 taking OIII.
The 2nd rid was: G11,RC8, TSRCRED0.8, IMX571 taking Ha and RGB.
There is quite a lot of nebulocity spread around the object itself and it is hard to say if it is real or just imperfections of my imaging train or processing, but I decided to keep it. With such long exposure, you can probably find Ha signal anywhere you point the telescope at
