What seems like a simple solution to dust on primary mirrors -- a piece of saran wrap gently laid over the primary to act as a dust barrier when stored, I've been told is a really bad idea, . . .
I've been thinking about trying vacum storage bags next year for a 10" Newt. The largest that they come in is 48" x 33" - too short from my Newt, but large enough to hold an SCT. http://www.merchantamerica.com/spacesaverbag/index.php?ba=home For a 10" Newt, I has thinking of wrapping the scope in 2 bags and then duct taping the seal and not evacuating any air. For other scopes that would fit in a 48" x 33" bag, you would not pull all the air out of the bag due to the crush hazard. Remove just enough to assure that the bag is sealed. Haven't actually done it yet - just an idea. - Kurt ____________________________________________________________________________________ Be a better friend, newshound, and know-it-all with Yahoo!
