We know that when we allow our eyes to become "dark adjusted" we see more. That, together with being at a dark sky site, makes a huge difference. Unlike a camera, which can do long exposures, and/or use software stacking to amplify an image, we only get what our eyes + brain process. 

 

I wonder whether there will ever be a drug that makes our eyes + brain do 'long exposure'? Could be very useful one day!

Probably the closest is when the eye doctor dilates you with those drops wink.gif

Sounds awesome but Iā€™d much rather have  X-ray vision.

If you can afford them, there's night vision devices borg.gif

I've never looked through them but those who have say the night sky is incredible drool.gif

Save up and get a Night Vision device. As Mr. T said, "Don't do drugs"

 

If such a drug gets developed, please don't drive after taking it. Imagine the LED headlights coming at you when viewed with enhanced vision!

Definitely exists. It comes on a little square of paper with a Mickey Mouse stamped on it.

A magic drug --- nope. That would be like some fuel additive could make your car fly.

 

But yes, Night Vision does what you describe. I have several ITT Gen 3 devices and love them, using true binoscopically (two identical NV devices)  at 1x, 3x, and the 16-inch binoscope at 74x... and also monoscopically on my 36-inch telescope at 132x. Few pictures showing some of that hardware >>>    Tom

TOM,

 

When you set up your night vision Binoscope "Loaded for Bear,ā€ don't you get a bit nervous at times? wink.gif

Unless you find a drug that effectively increases the eye/brain integration time, it isn't going to happen.  This time is on the order of 0.1 sec or some small multiple of that (a few tenths at most.)  Our brains allow us to reason our way to detecting more subtle aspects, stitching things together through repeated observation.  But that is nothing like stacking that imaging can do.  

 

It is impressive what the dark adapted eye can detect with such a small aperture and such a short integration time.  By comparison imaging gear looks rather poor if one applied the same constraints.

We get bears here occasionally. I put suet out and they go for that.    Tom

Yes,

Also certain over the counter allergy/sinus medicines contain the same (Phenylephrine) medication which in turn helps dilate your pupils.

 

I am often bothered by instant tears as soon as the wind starts blowing (even a breeze) which also turns on the taps to a runny nose. I will often take one *extra strength tylenol alergy/sinus tablet as soon as the symptoms start and if I still have problems a second dose 45 minutes later completely stops the nose and eyes from excessive watering.

 

Ultimately, this seems to make a noticeable difference in my naked eye observations.

This is over and above the fact that I have always had Very Good night vision especially while observing the stars.

Only time I've had those I couldn't focus.  You've to usually sit back in the waiting room for a while till the stuff works fully but that's boring because you can't read their archaeological collection of ancient magazines.
