While experimenting with a variety of "other-purpose" lenses. I discovered I had the makings of a really amazing micro lens in my telescope eyepiece collection. While you may not already have the eyepiece described, you can buy one cheap. I have seen them on eBay for $10.
The following Instructable shows how to create an adaptable mount for this eyepiece (or any 1.25" eyepiece for that matter) on ANY digital camera. My total financial investment, including the eyepiece, is $25. I could have bought a ready-made adapter for a mere $200. That's more than I bought the camera for on eBay.
And if that is not enough for you, this Instructable requires no special tools, like laser cutters, oscilloscopes, SLA rapid prototype machines, nor nuclear centrifuges!!!
Step 1: Gather your tools
1. A compass with one sharp point.
2. A rotary tool, like the Dremel, with a cut-off tool, small drill bit, and grinder. (handy, but not mandatory)
3. An X-Acto knife or other utility knife.
4. Needle-nose pliers.
5. A very small screwdriver.
6. A can of flat black spray paint, if desired.
7. 1/8 inch black crepe tape (optional)
8. Black marker
9. Fine sand paper
10. Small rubber bands
11. Needle file (optional)
This is what used. However, being the ever-resourceful people that you are, feel free to substitute as desired.
