Description

Hello Friends,

again a very small object. I see there a "Stellar Sweets". Don't get seduced!

Also don't get seduced to zoom in too much. Since it is very tiny, you quickly get into the "grainy" level. But even Hubble has only very little details, so I am quite satisfied.

The challenge (like almost all PN) is the huge dynamic range. Therefore I had focused on the outer areas of the PN and the faint arcs, since most images show basically the core. Also I have missed in many images the significant Ha component, which I have tried to add. This leads to an uncommon color palette for this PN, but I think it is justified, since even in RGB some regions get "pinky".

The data was collected during 4 nights.

Please enjoy!
Rüdiger
