Those skinny, long focal length, refractors are almost painful. They would have been frustrating to use because they had very little magnification. Over thirty years ago we bought our son a 50 mm Tasco refractor for around a hundred and forty dollars. That little telescope would have out performed Galileo's wonder by a factor of ten at least.

Here is what it looked like:

That telescope was a piece of junk but it was what we had. The thing had no motor drive so whatever you were looking at rushed out of the eye piece because of the Earth's rotation. It made us appreciate all the better telescopes we bought over the years.

Yeah,and it only took roughly 1000 yrs from the first recorded study of optics to Galileo to come with a useable telescope.Talk about old school hi tech, it had 18degree view with a magnification of 8X.The ones made before then were worse...

Ahh, I remember the first time I saw the Northern lights. I was farther North than Yellowknife, in Rankin Inlet.

Looked like this:

I've never seen them, these photo's are neat , but I always find myself thinking that the lights are photoshopped. Enough ppl have told me otherwise

No, they really are that vivid. Green, white, pink, bluish...they are quite spectacular. The buzzing sound you can sometimes hear just adds to the whole experience. The farthest South I've seen them is in Fredericton.

Oh,I believe you ( at this point ,another brick to the pile, as it were).They WERE visible in Sth Ont. in the last 10 years ( not sure when ) just not by me.They were ( I hear )rather faint.

Something like this:


On a clear night it might have been difficult to see from the space station. A bit of cloud would have made it impossible.

Hey, I'm just glad I don't have to pass grade 12 algebra again.;-)


I never did, mathmatically? well give me a brown paper bag and a pencil stub, I'd stii have to average it out after three attempts ( thank GAWD for calculators and computers)
