Quote:I sanded off paint from the last 0.4" and used a piece of wood to hammer in the backplate till it went in all the way (about 0.5"). Screwed in the A-P focuser, inserted a laser at the focuser end, a circular piece of cardboard cut to fit the tube over the first baffle at the other end, and this is what I saw. It's hard to see but the small circle drawn in pencil is 0.4" in diameter so looks like I'm only 0.15" off from the center. Sweet! The laser was about 53" away so I guess I hit about 0.15/53*57.3*60=9.7 arcmin. I think that's plenty sufficient. E.g. for my f/9 refractor, depth of focus is 0.18mm while this kind of tilt will change focus at the end of a 50mm field by only 0.07mm.Tanveer.
