AMEN I did dodge a bullet but also learned lots about the Burgess 127mm. I had painted over the registration pencil marks BUT got my diamond engraver bit and marked the alignment before I separated the elements. I have taken the scope completely apart as well as the new Moonlight Tri-Knob focuser, I'm optimizing the scope for solar work and there are many things that I can do to improve the contrast and the only way to do this, is take it apart. I have found the Burgess 127mm to be solidly built, well made and very crisp w/ minor color fringing for being an achromat. As soon as the microfiber cloths dry, I'll put it all back together and not touch the lens cell for a year PROMISE!! Needless to say, I was really down when this happened I usually don't make big mistakes. Aloha Rob
