[LVAS] Astro-Goggles

[Jim Gianoulakis]

Never anything specifically for night vision but I did use a pair of ski
goggles with a red lense for many years. Functionally the same concept
and very useful.

All,



I purchased this pair of astro-goggles many year ago. They seem to be
unavailable at current. Most amateurs today have never even heard of
them. 



If you are unfamiliar with the goggles, they can protect your night
vision if you have to use a flashlight or go back into your house. If an
object is extremely dim I can both sketch and take notes intermittently
while observing. I observe through the eyepiece and then remove them for
the intermittent sketching and notes. 



Using a red light can reduce your dark adaptability significantly for
the longest time. I also put them on while selecting a different
eyepiece. Be advised, you cannot walk in the dark and you "definitely"
could not drive with them on. 



If you remove your eye from the eyepiece and do other things with a red
light you will not be able to see that 13m star or 15th magnitude
galaxy. I put them on in the house at least 15 minutes before I go out.
Your time to dark adapt will be greatly reduced.  



Does anyone own or is familiar with these goggles?



This is an important part of "optimized" observing to see the faintest
details possible.
