You have now assembled a simple refracting telescope. After the diagonal would be way outside the focal point. You'll need two magnifying glasses that are NOT the same size. [1] X Research source If the magnifying glasses are the same size, the telescope won't work. Make sure that the system can focus. A few pieces of PVC pipe will be the biggest expense for this DIY ā€¦ Attach the lens element to the end of the diagonal (the end that will stick into the lens). The design had no intermediary focus, thus resulting in an non inverted and upright image. I needed a Barlow lens in front to shift the focal point back far enough to accommodate the extra length. After some searching, I realized that they were very hard to come by. If not, try moving the Barlow out a bit. Let it dry. Gather all your materials.

A much better (and easier & a lot cheaper) way to convert a camera lens into a scope is by using an eyepiece with an erecting element already built in. Mark that orientation. It will be a little weak on magnification though. Nice! If there's any bit of the sun showing, you'd need a filter to not go blind! It used a convergent (plano-convex) objective lens and a divergent (plano-concave) eyepiece lens. It is a bottom-of-the-line Celestron ($40) 5) A telephoto lens. 7) A 1.25" hole saw. Glue the diagonal in place. You'll want the part that holds the eyepiece to be outside, and the shiny chrome part of the diagonal on the inside. I had found out that putting a magnifying and minimizing glass together gave the sort of effect that you have in telescopes. (Some zoom lenses have lens elements right near the opening, which is true of my Canon 85mm to 200mm lens and you'll have to figure out how to get that to work). 10 years ago Mine did. I don't see any pincushion effects, stars are very sharp, and colors are fairly pure. Diagonal barrels are often threaded inside to accept filters. on Introduction. You can get the stuff cheap at a local astronomy club swap. Don't you need filters for that? Glue the other framed lens to the end of the larger tube. I use a 25mm Celestron Plossl for wide views, and a 10mm Celestron Plossl for high power. DIY (Do It Yourself) Telescope Astronomy Making has 10,313 members. 2) A telescope eyepiece with a 1.25" barrel (the most common standard). But why would I want to turn an expensive telelens into a scope? Did you make this project? Reply - DC. Pointing the thing with a generic tripod (no slow-motion controls) is pretty tricky. You won't be able to change it once the glue sets. The lens are situated on either side of a tube such that the focal point of the ocular lens is the same as the focal point for the objective lens. Reply I bought my 45deg one from Orion (~$45). Unscrew the lens element from the Barlow. That could help with lenses that have back element further back and also adjusting for various lenses gets a little easier. 5 years ago Since the clear aperture of the lens is about 65mm, I could probably go to a 6mm eyepiece and still get more out of the image, but my tripod would be extremely hard to aim at 130x. For a 45 degree one, you want the angle to point away from the tripod mounting hole on the lens. , since magnification is ~7x through the eyepiece is a bottom-of-the-line Celestron ( $ 40 ) ).
