Sky Instruments FINALLY has a Website, although it appears to be a work in-progress at this stage: http://www.antaresoptical.com/index.htm There is no direct contact info, only a fax line for dealers, although several US distributors are listed. Very few products are listed yet, unless they have dropped a lot of things they used to carry as of a few years ago. __________________________________________________ Do You Yahoo!? Tired of spam?

My old club installed one at our primary observing site. I was never convinced of its effectiveness. You have to run it day and night (with propane cannisters) and of course the CO2 plume is affected by wind. My feeling was that a lot of mosquitoes who were attracted by the CO2 found me along the way. There are plenty of people who swear by these things. I swore at it.
