Age and the ability to see in the darkPosted By Tom Bourg |
Hello Bill,
Probably all of the above compared to when I was a teenager.
This happens all the time at the observatory, btw. Us old guys are always talking about how much better the youngsters eyes are compared to ours and how good our eyesight was when we were younger..
I remember last year a buddy and I were using one of the observatories Meade 10" gps units on Jupiter. The four Jovians were visibla and we could just barely make out a dim star next to jupiter. A kid about 10 looked through the eyepiece and casually said that he saw five moons. He could see the star very easily.
I understand that if one can't focus to a point the light of the stars will appear spread out and thereby dimmer I also know that maximum pupil diameter also decreases, but I suspect more is working than that.
I didn't need glasses until I was in my mid-forties and my eyesight corrects to 20/20 but the kids can see better than all of us old guys. I think I can say that and no one will disagree with me.This weekend when I go I am going to take a poll and see for sure.
Good luck and clear skies.
