long shelf-life batteries
D-cells with a 20-year shelf life, called "Code Red". They don't activate until you twist the top, mixing chemicals inside the battery, after which they have a normal D-cell lifetime. Non-toxic, waterproof even in salt water, impervious to extreme heat and cold. Put in storage now, would still be good in the year 2025, according to manufacturers claim. Well-priced at: www.sciplus.com stock #36373 $5.50/pr. I'll be 72 when they expire- looks like I'll need to buy another set at that time... ;) __________________________________ Yahoo!

The speed at which technology seems to evolve, I'm going to start working on a "D" cell cannon. This way come 2025, when there are no longer any use's for "D" cell batteies, we can still have fun with them... ;) BTW, Isn't that Patrick (circa 2025) in the upper right hand corner of their web page?

Years ago, I worked with an engineer who'd done some government work. In their lab, they had a shelf full of very large and obsolete electrolytic capacitors. These were the big oil-filled cans, with a pair of screw-on terminals at the top. So they made a cap cannon, using a steel pipe with a pair of contacts at the bottom. They'd drop the cap down the tube, like a mortar shell. The contacts would meet and they'd start charging the thing with some honking power supply they rigged up. After a while, the electrolyte would heat up, the can would explode, and kablooie. They probably spread PCBs all over Virginia with that thing.
Hi Friends, I just posted a Mars photo on my gallery. It was taken from my SLC backyard last night. I am writing a story, and want to use the photo in it. Can anyone please give me an explanation for the lopsidedness and the blue crescent at the bottom? I notice that Don's recent Mars images have the same effect, so I don't think it's a telescope error. Thanks very much, Joe

Nicely done, Joe. Your pictures have a lot of surface contrast. The white cap is the northern polar snow cap. Your images are upside down. I can't tell if there also is a left to right reversal. See this S&T article with photos on the current orientation or Mars. http://skyandtelescope.com/news/article_1617_1.asp During October on Earth (Martian February), the northern hemisphere of Mars is nearing the end of winter. http://cmex.ihmc.us/cmex/data/MarsCalendar/orbits.jpg in http://cmex.ihmc.us/cmex/data/MarsCalendar/index.html On Oct. 18, the ESA Mars Express mission issued a northern polar cap fly-over movie. http://www.esa.int/SPECIALS/Mars_Express/SEM8T86Y3EE_0.html S&T also has a web-applet that allows you to determine the current orientation of Mars's globe and as an aid in identifying features. http://skyandtelescope.com/observing/objects/planets/article_997_1.asp Article with link that launches the web applet. Using the applet for last night, I am not able to match up your photo with features. Maybe other more experienced group members will know. Some good amateur comparative photos can be found at the ALPO Mars Section website: http://www.lpl.arizona.edu/~rhill/alpo/marstuff/recobs.html in http://www.lpl.arizona.edu/~rhill/alpo/mars.html - Canopus56(Kurt) Another global scale Mars map can be found at USGS: http://pdsmaps.wr.usgs.gov/PDS/public/explorer/html/molaintm.htm but it is not suitable for non-astronomical readers. __________________________________ Yahoo!

Thank you for your kind note, Kurt. I have replaced the photos with one that may show the shapes a little better; it was taken this morning at 12:35 a.m. I still am having trouble relating it to the map provided by S&T. Maybe mine is too fuzzy to see the features well enough to identify them. I don't know if the view is inverted or not -- I took it through my Meade SC, using the diagonal. The Meade Lunar and Planetary Imager was in the diagonal in place of an eyepiece. The cord was hanging down, as instructions say it should be. Maybe someone less dyslexic than I can figure out if that rotates the view or puts it upside down or whatever! Best wishes, Joe
The blue haze or blue clearing is a real effect. You can see it visually. Some people try to filter or process it out but it is real.

Not too bad for bad seeing. I still think the humble ToUcam Pro Webcam is one of the best if not the best for planetary imaging. See below: Hi, Due to the longitude of Hong Kong, I could only captured some shots near Solis Lacus under a very bad seeing.
