Hi Erick and Wavelandscott,
Thanks a lot for your help... I'm not a big risktaker and I don't want to "break" anything, so colliminating is one thing (and trying to get this right.. puh) and then trying to get this sorted by moving the main mirror back is another... I'll try and see how I go with the 1inch extension tube. Thanks a lot for your tips, great help. I hope you had a very good christmas.
