telescope

J brought a telescope for trouble-shooting, not able to focus. A reflector. The first problem he diagnosed himself, that was an alignment issue with the main mirror. Looking into the tube while he aligned the mirror using the screws at the back fixed that. The other problem was that he was attaching the eyepiece to a "balfour" tube and then to the eyepiece screw mount. Attached the eyepiece directly (it fit better, too) and the focus issue was solved too. Non-motorized, 72mm main mirror aperture, total magnification of around 400x, I think.
