http://www.surplusshed.com/pages/item/l3245.html I have mixed feelings about this lens; for about twice the money you could buy a real doublet corrected for infinity; on the other hand I've had good results with most copy lenses, albeit at low to medium magnifications. This might be a way for someone on a budget to get themselves into a 6" refractor relatively inexpensively. If anyone buys this lens, I'd sure like to take a look at it. (I already own a 5" doublet refractor, so I'm passing on it.) _______________________________ Do you Yahoo!? Declare Yourself - Register online to vote today! http://vote.yahoo.com
Y'all- With my job ending in April (still looking), a subsequent change in email address (now with DSL), and summertime activities (50 mile backpack in the Canadian Rockies) I disconnected from the group until just a couple of days ago. I saw this press release about glow-in-the-dark inkjet photo paper, and thought it might make some interesting spur-of-the-moment sky charts. But it costs $1 apiece for 4"x6" sheets. But for $2138, you could reproduce Burnham's and read it in the dark. Bob Grant http://www.brightec.com/press/press092304.php
Welcome back, Bob! Did you happen to pack a small scope or binos with you on your Canadian trek? Or were you far enough north for perpetual twilight? Some enterprising person should market printer cartridges with glow-in-the-dark ink. That should make the individual cost per sheet much lower, and would probably be easier to read at the telescope than the entire sheet glowing and the ink not.

Chuck- I elected to leave any valuables at home for this trip. I had to leave my camper unattended for six days, and didn't want to come back to a rude surprise in case it had been broken into. Twilight was long, but not perpetual. (What WAS perpetual last time was the rain.) The moon was bright, and I did get a pretty picture of it scraping the cliffs one evening. Daytime views were obscured by smoke from distant fires - the radio reported hundreds of forest fires in British Columbia and the Yukon. Still, when it cleared, it was some of the best scenery that I have seen anywhere.
