  • Thanks truemartian! Another helpful video

    Hmm.. I wonder if rubber-banding a few layers of red colored tissue paper over my flashlight head would work well enough..

  • @trenalune It could be worth a try.

  • @trenalune check my page.cheers.

  • hey i have a jvc everio hd 300 and i need to know hot to put red light vision or night vision on it! please help me i see ufos all the time and need to prove myself right!

  • @charlienethercoat094 Probably the best thing you can do as a UFO investigator is to become familiar with the night sky, the moment of solar system bodies, and typical appearances of air and spacecraft. This will help you identify a so called UFO. As far as night vision equipment goes, I do not have the technical know how in the area you seek an answer to.

  • @truemartian ok thanks anyway!

  • Can animals see red light? I bought special flash light with night vision option and used it on a raccoon , it didnt seem to react to it at all. The moment i switched it to normal light , it ran off.

  • @valkyrieseven That's interesting. I do not know the answer to that question.

  • Thanks for making this easy for a beginner like me to understand! Its made me want to watch your others to maybe FINALLY begin looking thru my big ol tube thingie that points at the sky.. I think you "Mr Scientist People" call em.. Microscopes

    anywayz, we're building a treehouse with an obs tower on top and i'm about a mile off the shores of Lake Michigan, so am hoping to really get into this bigtime asap! I am 51 and have a 6 yr old that i want to get Stoked about "Mr Scientist" things PEACE!

  • One more nice video truemartian!

    damn dark adaptation is hard to achieve in urban areas.

  • dude, good video, but seriously...can one say....long winded? this video should be at the most 1.5 minutes.

  • It may be a good idea to use bilberry and blueberry and those herbal health food suppliments with betacarotine, which are said to help improve night vision. We used to use red lights in photo dark rooms where the paper being exposed was ortho chromatic and not responsive to red light.

    Great pointers, thanks again, I'm going thru your play list. just commenting like nuts. I hope you don't mind.

  • I found an interesting site about red lights (and other colors) that preserve night vision, perhaps it's worth a look.

    It is not my intention to contradict anyone, obviously you can't believe everything you read/hear, but then again how much do we actually know from first hand experience.

  • It is well documented that the use of longer wavelengths of light preserve night vision. Its pretty much standard practice in the amateur astronomical community. In the 20+ years I've been star gazing a red light has served me well at night.

  • Sadly, there is so much light in the city, that I can see fine without any lights, and the only way to see any stars is to drive a far distance out of the city.

  • Astronomy is so cool!

  • Wow, You my friend are smart! If i ever find an asteroid not yet discovered, I will name it Truemartian. For my role model ;). Btw If Sirius is 8.6 lightyear's away are we looking at it 8.6 years ago?

  • We would be looking at Sirius as it appeared 8.6 years ago.

  • @truemartian WOOOOW! DUDE! Mr. Scientist, U ROCK!

  • so in other words, your vision would adjust to night with a red flashlight then with a white flashlight. So lets say I was using a red light to see at night but for reason it goes out. It would take me a short time to adjust my vision if I was to use a red light then a white light.

  • Any use of a white light will cause you to lose your night vision and you will have to wait another 20 minutes or more to become fully adapted.

  • I've heard that a blue light can help preserve your night vision too. do u know if this is true?

  • My educated guess is that it does not. Red light has long been established as the best way to preserve your night vision.

  • Thanks for your help :)

  • i have one of those red lights there very interesting!!

  • I never knew about that...thankyou for this vid, very helpful indeed. Oh and could we also put red cellophane over the torch?

  • Sure, lots of people do that.

  • cool

  • What i always find usefull for adapting to low-light situations is to just sit in my living room with no lights on. Eventually the little power indicator on my cable box will illuminate the entire room, that's when i know it's time to go to work.

  • Hmm... somehow I missed this post earlier, sorry Truemartian. 5 stars!

  • Another outstanding video! 5 4 U!

  • Thank you!

  • Thats verry informative! learn summink new everyday:)

  • Great video, can't wait for the next one... I dont even bother using a red light anymore, mainly because its to cold to even do anything much more than get out for 10 minutes and look at orion, or pleadies, or saturn... hopefully it will warm up in canada a little bit:(

  • I've had my annual orion look this winter ;-) I know what you mean. Luckily its been warm enough here in Ohio to get my 6inch out to photograph the moon.

  • As did I with orion.. got to colminate the dob also.. Still not warm enough to do anything other than point and shoot with the dob, as ill need warm weather to accuratly align the scope and get the ccd camera going with the comp
