I used an 80mm f5 short tube refractor with no luck, an 80mm F11 does a better
job. If your scope is rigid enough, you can use a guidescope, otherwise the
Lumicon off-axis guider will always do a perfect job.. at the expense of a bit
of vignetting on film.. 

Finding a guide star with the Lumicon newt off-axis guider is surprisingly easy.
