From a project I never got around to:
2 inch Lumicon 1.8x Newtonian barlow (corrector) I would assume that it being specifically made for Newtonians to mean that it corrects for coma. I am not 100% sure though because it has remained unused since the day I bought it from Lumicon.
It has a detachable eyepiece holder so you can use it either for visual or with a CCD camera.
$150 + postage.
