Thank you.

Uhh, that is without an autoguider, yes. Some people think I actually
moved the mount by hand. The translation of "manual guiding" (that is to
use a clockdrive, but no autoguider) to Dutch is "handmatig volgen".
It's a bit confusing I guess.

You're correct. I will work on it.

Exposere lengths longer than 15 minutes are propably out of the question
on my observing site. Though it was a bit foggy on the particular night
when I shot the images. With a transparant sky I think 20 minutes is
possible for objects near zenith. Of course I can always stack several
short-exposure images. I am a member of an astrophotography club. A
small group of this club goes once or twice a year to dark Southern
France to take images. Maybe I'll join them next time they'll go.
