How to build your own Homemade telescope Eyepieces for astronomy

In this video, i am presenting you my homemade eyepieces, that i've built over the past 4-5 years, using objective lenses coming from damaged binoculars. Those binos can be bought on the second hand market at ~10$/pc, and with two such binos you can make at least one great quality eyepieces, capable of field and color correction no other eyepiece on the market can do, in the same price range, and for similar focal length.
Doublets coming from eyepiece lenses can be used as well, in various combinations either among themselves, or with the objective lenses, producing a variety of focal lengths (FL) and apparent fields of view (aFOV).

On average, the production costs for one such eyepiece consists of: two SH binos (~10-15$/pc), one barrel (either extension tube, or salvaged from crappy eyepieces - ~7$), 3D printed casing (it depends on the size, complexity, and number of parts - say ~15-20$). The resulting eyepiece, even though quite "full of glass" (8 elements), will be capable of a long FL, a well corrected FOV, and quite a generous aFOV, that is very hard to match by commercially available eyepieces, in the same price range.

Casings design made in ACAD, lens renditions also in ACAD, video made using Veed.io, background audio track made by myself in MPT. Track can be found here:

I hope you enjoyed watching this video, found something interesting in it, and sparked some inspiration for your own creations.

Thanks to Red Henry for the idea, shout out to all amateur astronomers community out there, and to all those interested in ATM (astronomical DIY).

Clear skies!
