Howdy Cluster,
How does the telescope perform for visual observing? Does it give you reasonable views of the objects you are trying to image? A small reflector like you have has only a very low theoretical magnification ability, say, 300 or so(guessing) so using a 3x Barlow may also be ruining your images. As suggested in an earlier post, for imaging(and a newbie), I'd seriously consider just putting the camera in the focuser draw tube(wide field) and see what that does, however your image is indicating you may have done this already. Still, you need to check the scope in a visual way first, forget imaging, collimaters and lasers, what does a star test reveal. I am a member of ASSA(Astronomical Society of Sth Australia) and if you so wish I am prepared to help you with some basic tests first with my limited knowledge before you really go tearing your hair out.
PS:If & when you sort this out, you could also join ASSA and the Deep Space Imaging Group that we have to get you a bit further along
