Description

Dear Friends,

after a long time of terrible weather, there were a couple of clear nights. Not perfect, but good enough.
I grepped the chance and re-visited an old friend: NGC 3718. This time with the goal to gather enough photons for a decent image.
The data for this image was taken over 5 nights.

Please enjoy!
Rüdiger
