I still think colors are most important. Especially when Joan's telescope color, matches her car color. And Nate's red scope with the white end is especially nifty. (Guess you had to have seen the video to get this LOL). ;) Cyn Chuck Hards wrote:
Many of you use the red LED-equipped pens for taking notes at night.
I just received a green version, apparently made by the same company, but the body is turquoise rather than black.
There was some debate awhile ago on whether red is really the best "color" for an astronomer's light; some folks claiming that intensity was more important than wavelength (color), especially at the very dim settings we normally use. I must confess that I prefer a green or white light for reading charts, from an aesthetic standpoint alone, but tend to use red just to avoid irritating fellow observers.
Now there is a choice. I plan on trying both out at the eyepiece to see if I can detect a difference in my dark adaptation, aesthetics aside.
Amercian Science & Surplus has the green ones, stock #34489.
