Anyone know if Chris Johnson is on this group? He lives out in Goodyear and might be able to do it.

It would be like 120 miles round trip for me. Your suggestion is one of many feedbacks I'll be sending to Ann on Monday. I'm guessing she could get a cheap spectroscope at most any hobby store. And I can send her an image of what a mercury vapor spectrum looks like. Anticipating the need, I've already uploaded it to my website.

At close to $4 a gal and 15mpg it would be too expensive for me. It's too bad the people cannot just use a cheap spectroscope. You d not need to know much about hte spectrum. Just look at various lights of know type and compare to the light in question. > > > Jeff > > Hopkins Phoenix Observatory > (187283) > Counting Photons > Phoenix, Arizona > www.hposoft.com/Astro/astro.html > -- See message header for info on list archives or unsubscribing, and please send personal replies to the author, not the list. -- See message header for info on list archives or unsubscribing, and please send personal replies to the author, not the list.
