After a very long summer-break in Astrophotography,
I found myself with time on hand on a clear evening. After
I did a series of 4 300s images for the Plejades (see below)
I set the scope up to capture a few light frames on M42, the
Great Orion nebula. But while I was sitting in the living
room trying to get warm again, watching the Soccer Champions
League, the D200's battery ran empty, and I ended up with
only one long exposure. I used the single 300s exposure with
a much shorter exposure to get some detail in the very bright
center of the nebula to get this picture.

While waiting for Orion to rise out of the murky atmosphere
near the horizon, I took a series of 4 images of the Plejades.
Trying to focus the camera on the 80mm drove me crazy this
time, after 30min of fiddling with focus I managed to convince
myself that the image is now sharp enough (using a Bahtinov
Mask) but after I downloaded the pictures to the PC I found
them to be very unsharp. I got some information from the scope
vendor on how to adjust (basically) loosen the focuser, let's
see how it works out...
