Another test session after moving everything over to SGP. Everything seems to be working perfectly as of now so the real work can begin when we have clear skies again here in NL :-).

This image has been fully taken with a full moon.

I happy that things are looking much more sharper now, probably because of the auto focus system and the use of a monochrome camera.
