Not strictly true, Don, again it's a matter of technique. The trick is to use total immersion and liquid flow only to loosen particles and remove them. When most of dirt is gone, a good grade of lens cleaner, alcohol, or distilled water can be used for touch-up and rinse. Of course this requires removing all metal parts from the glass to be cleaned, to avoid trapped moisture and mold, which also means you must know how to re-collimate your telescope from scratch. Something every telescope owner SHOULD know anyway. If there is no dust on the optics, the scope isn't getting used enough! ;) C. __________________________________ Do you Yahoo!? Yahoo!
