Scopkes and smoke
Ok, so I went ahead and bought my wife an LX90.. it arrived this morning
but the previous owner smoked and the box smells awful. But that's a "so what". Could the smoke have affected the telescope ? And if it needs cleaning, where does one get that done ? Thanks Adrian |

General guidance WRT cleaning telescope optics is; don't. Unless the optics are filthy there'll be no noticable degradation in performance. Telescope house sell a number of scope cleaning kits: http://tinyurl.com/a6fnl . I bought the AC496 to clean the corrector plate (top bit of glass on the LX90) when pollen starts covering it. Hope you and the wife enjoy the scope. Hope its everything you expected. Regards Chris |

And if it needs cleaning, where does one get that done ? Thanks Adrian Hi Adrian, You might find that the corrector plate is quite dirty due to the tar (and other lovely stuff) in the smoke. This can be a real problem as bits of dust that would normally just fall off the 'scope will stick. You might also end up with some grit/dirt on there as well :-( We had a similar problem to this with the OU telescope (although it was due to tree sap/exhaust fumes in the air rather than smoking) and we cleaned the corrector plate with a mild soap solution. The flat structure (i.e. what you see when you look a uniformly illuminated field) before we cleaned it was terrible (http://physics.open.ac.uk/~jdtanner/Before.jpg) so we didn't have much choice. After cleaning, the situation improved significantly with virtually no flat structure due to dust/grit (http://physics.open.ac.uk/~jdtanner/After.jpg). All the best, JohnT http://physics.open.ac.uk/~jdtanner |

Regards Chris It is worth also asking, whether it is the scope, or the packaging, that smells so bad. It is possible (for instance), that the packaging was in a cupboard under the stairs, while the scope was out in the garage. The packaging could smell foul, yet the scope wld not need anything done.
