Your projects are great ideas for showing kids how to make things. But could you please number the titles of Reversible Picture and Upside-down Telescope? That would make it so much easier to find where to begin each step of the project. Thanks very much.
Any way i can make the upside image come just normal.
Oh and do both the mirrors have to be the same. If it is possible can you please tell me the fattest of the mirriors you have. How and can you see the moon with it and if you see the moon is it in a good view like good zoom up and every thing.
to make it right side up you use a diverging lens as the eyepiece (the small lens)
The lensen don't need to be the same. On the contrary, the objective must be as large as posible, with a big focal length while the eyepiece must be the oposite. This answers your point about zoom, the power of the scope is given by Fob/Foc, where Fob is focal length of the objective and Foc is the focal length of the eyepiece, the resoling power (the "fine detail" you can see) is given by objective diameter
What ya need is an 'erector' lens. Otherwise it is an astronomical telescope, for which purpose it don't matter seeing stuff upside down. I think Lol!
if you use one magnifying glass, the image wont be upside down. if you use two, it will be upside down, if you use three, it wont be upside down, 4 upside down, 5 not upside down, 6 upside down. et cetra.

Freakman420 is wrong. Try adding a third lens. Does not work.

You need to change the title in something like "Part 1 of 6", because people who don't visit your site will have no clue where to start!
