    Im thinking about attempting to make a Thermal Vacuum Evaporation Chamber this summer. Anyone ever made one or have any sources I could use?

    To make a Vacuum deposition chamber is very difficult; important is not only to evaporate and deposit the metal, but also uniformity of the deposited layer, and the surface of the deposit (1st surface mirror). I designed and built a prototype
    (for Semiconductor Industry), and in order to achieve uniformity, the target was rotating ( non constant speed; deposition is a function of exposure time) in order to have uniform exposition.

    If everything else you try fails, get a better telescope..........

    RawThinkTank, please dont post threads in other threads. Thats why you made it a seperate thread, so people can go there a talk about it. Besides, this thread isnt for the theoretical.

    Thanks

    I don't think using soap is such a good idea. I once had multi-coatings on my glasses. After a few months, the multi-coating was washed off because i use soap on them.

    The coatings on your glasses and the coatings on a primary mirror are two completely different things.

    And did you notice I said a "drop in the bucket."

    How can i make a Binocular type Telescope work like Astronomical Telescope using house-hold items?

    A study on how the size of a parabolic mirror affects image quality in bad seeing conditions.

    Check out the article in 'Dual 6 Inch F/15 Cassegrain Binoculars' in Sky & Telescope Nov. 1981 issue or the 1990 book 'Touring The Universe Thru Binoculars'. That should move you in the right direction.

    Or you can look up the 'best' Hubble archived space photos at:

    http://www.msnbc.msn.com/id/6955261

    and download them into your computer. That way you can save yourself a lot of trouble, plus the cost of a telescope, telescope accessories, CCD camera, computer/monitor and all the accomodating software that goes along with it. Try it, you got nothing to lose.

    Actually, your photos of Jupiter & Saturn are not too bad. I think the Hubble's are just a little bit better though, but it's really hard to tell after you've had three or four glasses of Jim Beam. Have you taken any of the Eagle Nebula lately?
