ASTRO: Two planetary nebulae in one image

The two planetary nebulae PK329.0+01.9 (right, blue) and PK329.5+01.7 (left,
red) in the constellation Norma fitted into the FOV of my Atik 383 at the
12" ASA astrograph. Only the brighter blue PN was on my list, but
fortunately I noticed that I could fit the other one in too.

Object: PK329.0+01.9 and PK329.5+01.7
Optics: ASA 12" Astrograph, 1069mm focal length
Camera/filter: Atik 383, Baader LRGB
Exposu 16x5m Lum, 4x5m RGB each
Mount/guiding: ASA DDM85/guidescope/Lodestar/AstroArt5
Location: Tivoli Namibia

That must have been an interesting processing challenge! Did a great
job. Must be a pleasure to process dark sky images compared to what you
are used to in Berlin.

I don't know that part of the sky but sure don't remember hearing about
these two before. They may be both planetaries but the similarity ends
there. Quite a contrast between the two. Even as to central star.
They appear about the same size but that might be due to distance. I'll
have to do some research on these two though doubt I'll ever be in a
position to take an image of them.

Rick,

actually I just processed the image so that the brighter PN was as bright as
it could get without burning in. The red PN is a bit hard to find if you
don't know where to look for it...
There are two PN in the northern sky that have a similar size and distance,
PK136.3+05.5 and PK 136.1+04.9 in Cassiopeia. I have imaged them last
autumn, but conditions were very bad, so they are barely visible in my
image.
