Meade Conference Call

Meade stock closed today at .65 and had been falling all day. It is my understanding that one of Meade's largest stock holder is shopping their stock holdings in hopes that it can get out from under a $7,000,000.00 loss.

What is the colour of Ha anyway?

Posted By ROBERT MOORE

Greg I talked to a my buddy ( Jim Brunell ) about your post heres what he sent back "I think your confusing Ha with entire spectrum of ionized hydrogen gas. At 656.3nm, Ha is a very deep red, it is almost at the threshold of infrared at 700nm.It is not an "orangy-red". But Ha is not the only emission line present in a cloud of ionized hydrogen.
Where Ha is present, you will also find Hb, but it is not as strong a line as Ha. Hb is a blue-green, not a "sky blue". You will also find the whole retinue of lines of ionized hydrogen, including Hg (violet), Hd (violet), He (deep violet), and others, continuing down in wavelength, but not very strong, so they do not contribute very much to the overall color hue. When you mix deep red Ha at 656.3nm with blue-green Hb at 486.1nm you get an electric pink color.?

Hope this helps, Jim

So their you have it,
