Re: [Utah-astronomy] Red Light Myth
Excellent post, Fletcher. Thank you. It confirms what I've experienced over the years. Intensity is more important than color. I would like to add that people who are astro-imaging don't really even need to be truly dark-adapted anyway. Keeping one's eyes at maximum sensitivity is advantageous for the visual observer who is working at the very limits of a particular telescope, or doing unaided-eye observing, where a fraction of a magnitude can be critical to noting a detail, or not. Someone who's primary motivation is taking images or data need not be overly concerned with it. The fact that you are spending most of your time looking at a screen and not an eyepiece, obviates the true requirement for deep dark-adaptation anyway. So, don't worry so much about it if you don't really need it. It's not a priesthood and nobody is going to rat you out to a higher authority if your flashlight or headlamp is just a tad brighter than your buddy with the 24" Dob and a copy of the Millenium Star Atlas might think necessary. ;o)
I mostly try to do astroimaging, but I want to preserve as much of my night vision as possible. I like to stare at the stars when I can. -- Joe --- On Mon, 8/30/10, Chuck Hards <chuck.hards@gmail.com> wrote: From: Chuck Hards <chuck.hards@gmail.com> Subject: Re: [Utah-astronomy] Red Light Myth To: "Utah Astronomy" <utah-astronomy@mailman.xmission.com> Date: Monday, August 30, 2010, 5:21 PM Excellent post, Fletcher.

Be careful most of those stars are white and blue light. Very few red. :)

Yes, good post. Here is a link for the flashlights Fletch talked about. They have a a green/infrared led combo that looks interesting. http://flashlightsunlimited.com/rigel.html Erik Excellent post, Fletcher. Thank you. It confirms what I've

The first link did not go directly to rigel flashlights, this one should. http://flashlightsunlimited.com/rigel.htm
