  • this work???? please tell my

  • hello!! Thanks for showing us how to make it.

    Cool video man.

    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.

    THANKS

  • 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

  • @DarkTemp0

    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!

    :)
