Hi Erwin
Have you tried setting up your scope in daylight? You'll need to find something at least 100m away to aim at. If you are using a normal Newtonian scope the prime focus should be at a same distance away from the primary mirror as the mirror focal length. Measure from the primary mirror to the secondary and add the distance out to the focus point. That's about where the plane of the CCD should be (without a Barlow of course).
I've ordered the IR filter on ebay for $32 + $10 postage from New York.
I can send you the details via PM if you want.
