Then adjust the DSLR plane to shoot the beam exactly co-linearly back through the film plane. A bit of fussing with this, but if the DSLR lens axis is precisely orthogonal to the sensor (high quality DSLR should be I suppose) then you should have a pretty good alignment. As I recall in your setup you may not be using a glass plate for film mounting - but maybe you could substitute one. The laser pointer would be temporarily substituted for the normal light source. Just thinking about alignment issues when I start fiddling with this.

I use a Versalab Parallel to do exactly that. It works a little better over longer distances, but it's still a big help.
