What can I do with this telescope?
I have a telescope that I got today for $15 from a yardsale. It was only $15. I don't really know anything about telescopes so I was wondering if you could tell me what I actually have.
This is what it says on the main scope:
Focal length 600mm
Diameter 50mm
I also have:
Two eyepieces/lenses, labelled H6MM and H20MM.
One long plastic thing labelled 1.5X Erecting Eyepiece. This turns the image the proper way up, otherwise its upside down. Does this actually help with magnification? I've looked through it and it just gives a blurry image.
How do I work out the magnification that each lens gives? How does this compare to my 10x50 binoculars? Thanks.
It's a refractor.
Most telescopes give an "inverted" image when you look through them. That's not really a problem when you're looking at the sky, but makes things harder when you're looking at stuff on earth. It looks like the erecting eyepiece would turn things the "right" way, and also provide some additional magnification.
If you looked through the other eyepieces, and then through the erecting one, they probably don't focus at the same place, so you might have to considerably refocus the scope. If you can't get a good focus through the entire scope's range of focus adjustment, I'd just put that eyepiece away and not worry about it.
The magnification power is easy--just divide the focal length of the scope by the focal length of the eyepiece. You're two eyepieces would give you 30 and 100X magnification, compared to 10 for your binoculars.
