Martijn thanks, i use the classic LX200 mount which i modified in many ways.
it's capable of tracking for more than 180 sec without using a autoguider.
I also trained the PEC last spring which also helps a lot.
But it still needs a lot of fine tuning.

HI all,
Here a quick shot of the centre of the eagle nebula.
10 x 90 sec
H-Alpha filter
10" SCT.
Homebuild CCD cam cooled to -14degr.
the sky wasn't that clear (lot of moisture which makes the stars bigger).
Will try again with more transparent sky.
Processing was done in Maxim and CS3
thanks for looking,

very nice dirk! my mount has problems with tracking accurately for more
than 1 minute, even at
f/6.7. What mount do you use?
