Telescope Making Supplies

As you read some of the older books on telescope making you will understand how serious the quality control problems were, and the great pains taken to purify abrasives. Today, modern technology is capable of producing consistently high quality aluminum oxide which has practically replaced the natural forms for precision optical work.

How to Make a Lens from Scratch (Like, Literally Rocks and

Mar 09, 2019· Adam's DIY pinhole camera and finished zoom lens were made entirely from scratch. It's absolutely incredible to watch someone mine, extract, and melt down copper, and then use borax, sand, and soda ash, all of which Andy collected himself, to make glass, but damn...knowing that it took months of grueling work, dozens of attempts, and over 30

A refractor employs lenses at both ends while a reflector uses a curved mirror at one end and a flat mirror at the other. It Is virtually impossible for an ordinary person to make his own lenses for a refracting telescope; but if you can get some lenses, perhaps from a war—surplus store, you can make a small telescope.

Christiaan Huygens and his telescopes

for himself, Christiaan designed and built his own lens-grinding and -polishing machines (Figure 2). One of the greatest problems with lens grinding is to make a suitable lap by utilising metal moulds with a perfect spherical shape. Another problem for the Huygens brothers was to find glass of high quality and homogeneous in structure.

The best wide angle lenses for astrophotography 2020 DIY

Usually wide angle tends to refer to a lens that is wider than 50–25mm. I like ton consider any lens that is wider than 35mm a wide angle. For full frame cameras, most wide angles are somewhere in the 14–30mm range, with anything wider than 14mm generally being considered a “fish eye”.

1791: Telescopes: Refractor vs Reflector explain xkcd

Grinding a high quality lens is more expensive than producing an equivalent mirror crown glass, which is needed for good quality telescope lenses, is expensive. Less compact In theory, a refractor could be made compact, but the image quality would be awful, because the lens would have to be extremely fat. The longer the telescope is, the less

Dokas Photos – How To Ground Your Own Glass

I was familiar with lens grinding, having ground my own 8" reflective telescope mirror in high school. I even had on hand some of the grits packed away in the attic. I visited my local glass supplier to find some glass similar to my cracked ground glass to use as a blank.
