All Skywatcher Newts have sufficient back focus for AP. Most others don't.
I assume that the tube that accepts the eyepiece on your Lightbridge's
focuser can be unscrewed. Aim your scope at a distant feature such as
tree and hold your camera up to the opening and see if it will come to focus leaving enough of a gap between the camera and the focuser to
fit the adaptor. Alternatively, ring or email a Meade dealer.
