HI all,
If this is a 16" Lightbridge you only have to get a spacer or extender for the focusser. Point the scope at the moon, point your lensless camera down the focusser barrel and slowly draw your camera away from the focusser. If it's like mine it needs a spacer to extend the focusser length by about 35-50mm. Then it should be fine! Bintel or Andrews Communications should be able to help you.
