A new project, Jones 1 planetary nebula





Jones1, colorized O-III, 5h 20min.

Jones 1, PK104-29.1,  is a one of the dimmest planetary nebula. It locates in constellation Pegasus.
I started this project last night and didn't realize how dim this really is. In this image there is 16x1200s O-III exposures, 5h 20min. ( Baader 8,5 nm O-III filter) and it was barely visible in any of the subexposures. 
I will shoot more O-III later  for this. There is some H-alpha emission and I will shoot that later too.

I like the "mystique" outlook of this nebula. 
There is not too many images of this around due the extremely low surface brightness, even though it has a largish diameter to a planetary nebula, about Four arcminutes.

Technical details:

Stacked and calibrated in CCDStack.
