Re: [Utah-astronomy] Dark sky friendly porch lights

Another suggestion is a screw in photo cell between the socket and the bulb if you leave for work before daylight and return after dark. You turn on the switch before you go out the door and have light to get to your car and then it goes off at dawn and is on when you get home and you can turn it of at the switch when you get in the house unless you are expecting guests. I think it was under $10 at Wal-mart. Motion detectors with built-in photo cells are a little more but you don't have to remember to turn them off. > [Original Message] > From: Steve Trottier <strottier(a)novell.com> > To: <utah-astronomy(a)mailman.xmission.com> > Date: 1/25/2005 10:26:03 PM > Subject: Re: [Utah-astronomy] Dark sky friendly porch lights > > Besides getting a dark-sky friendly fixture, the other thing you can do > to help, obviously, is to not turn it on.

Charity Astro Auction
by Chuck Hards 25 Jan '05

25 Jan '05

Barney's question was timely. Rob Ratkowski and I have been tossing around ideas for a utah-astronomy charity auction, proceeds to go to a recognized tsunami relief organization. Cynthia has already given her permission to use the forum for this purpose (thanks again, Cyn!). Unfortunately I lack the skills to pull this off properly and we could use some help, both technical and otherwise. I'm starting school soon and will have very little email time after Feb. 10th, for about four months. We would like to solicit donated items from list members, maybe auction them off individually or in lots, whatever makes the most sense. I'd like to see donors send off the items to the winners themselves, and donate the shipping charges to the cause. I'm hoping folks will see this as more of an opportunity to express some compassion rather than strictly a chance to pick up a bargain, but you never know, maybe both motivations can be served. The donation phase should be fast, so the actual auctions could be held and the proceeds donated to a charity quickly; there is a great, immediate need. Comments? Suggestions? Volunteers? Thanks everybody, this list has some fine people on it. __________________________________ Do you Yahoo!? Yahoo! Mail - You care about security. So do we. http://promotions.yahoo.com/new_mail

The "GlareBuster" fixture also looked interesting. It has a product endorsement by comet hunter David Levy and can use a high-efficiency long-life bulb. http://www.theglarebuster.com/ http://www.darksky.org/fixtures/motsensec.html One "GlareBuster" model has a motion detector cut-off: http://www.darksky.org/fixtures/motsensec.html This is the type of motion-detector light, that I own: http://12.153.20.71/heath/mainProduct.asp?page=security&type=Motion+Sensing… A simple clip-on shield to an existing light can cut-down on glare from these older units - although I have not seen these locally in Utah: http://www.parshield.com/index.html http://www.darksky.org/fixtures/mods.html (see 1/2 way down the page) If anyone knows where these clip-on shields might be available in Utah, I'd like to hear from you. - Canopus56 __________________________________ Do you Yahoo!?

P.S. - The RAB Electric Manufacturing, Inc. Model: WP1C Series looks particularly interesting. It has an adjustable shield - a nice feature I have not seen before. http://www.darksky.org/fixtures/wallutil.html Personally, I just use security lights with built-in daylight/infra-red sensors. These IR detecting security lights are always in "zero-light pollution" mode unless there is someone on the doorstep, although they look ugly for a front-porch application. Such security lights cost about $25 each on sale, when I bought them about six years ago. IR detecting security lights are a nuisance when trying to observe from your front porch. The security lights can be forced into zero-light-pollution "off" mode, when setting up a small refractor for a few minutes of relaxing post-work lunar viewing, by directing a red pointing laser into the light's daylight detector. The security light's daytime sensor is triggerd by pointing the red laser into the daylight detector-switch. Rubber-band a laser red construction level ($19 at K-Mart/Smiths) to a camera tripod. The red-laser construction levels have the convenient feature of a positive on/off switch. Ordinary red laser pointers with a push-button spring-loaded switch can be rubber-banded to a camera tripod and held in "on" mode with an $2 spring clamp (available at K-Mart/Smiths or any hardware store). - Canopus56 __________________________________________________ Do You Yahoo!?

Re: Signal sender?

Patrick, don't sell it. Buy a battery-powered TV camera, connect it to the signal sender, and put it in a tree over by the car-wash when the weather gets warm again! ;) __________________________________ Do you Yahoo!?

Looking to buy..

I am in the market for an extremely powerful Atmospheric Pressure and Weather Regulator. If any of you are, or are in contact with, an evil genius with access to a well tested model please contact me. I request that it not be connected with any previous world domination plots. I just finished watching the weather and the forecast for the next week was, "Grey with a chance of Light grey followed by a slight chance of going to Park City where it is not grey".
