"Changed the adapter on the camera to a 1.25" nose so that it slots into the barlow.
Put the whole lot on the scope and focus is spot on in the middle of the focuser travel.
Thank you very much"

" typically the barlow lens is inserted into the focuser sleeve first.
In addition to amplifying the image 2X with a given eyepiece it also increases the focal length of the telescope ( that's actually how it works) and moves the focal plane back a little in the process. "
