Description

After a long time, I re-animated my 25 years old C8 to try the Pacman Nebula.

In the end it turned out, that the SC-optics is not really comparable with well corrected Apo-lenses which I prefer. This was no surprise to me. The only reason for me to use the C8 is the longer focal lenght.

Only 3.2 hours total exposure, which is a bit too less for this object.

The result is ok but not really breathtaking.
