Mirror grinding Telescope making
Once the back is flat, we can start to carve the front into its spherical shape. The theory here is that if you rub 2 circular blanks of approximately the same hardness with an abrasive in between, you will end up with a concave blank and a convex one.... Parts go out of alignment, causing the mirrors and lenses to be out of focus. You can prevent this by careful handling. A foam-lined, wood storage case will help the protect your telescope from minor bumps and bangs, so your next star-gazing session won’t be wasted on telescope repairs.

The standard kit includes all the finished optical components needed to build a Newtonian reflecting telescope; namely, the primary concave mirror, the secondary flat mirror, two eyepieces of 25mm and 12.5mm focal lengths, one Barlow lens that increase the power of any of the eyepieces from 1.5x to 4x times, a 25mm diameter objective lens and eyepiece to make a 6x power finder telescope and... The Cassegrain Project The Cassegrain telescope is probably the first type telescope that the ATM would like to make after mastering the basic Newtonian telescope.

You really need to build this telescope as a necessary step towards understanding the solutions employed in the second and improved telescope model. In the section "From Lenses to Optical Instruments", you saw how a telescope works; here I simply remind you that the objective lens produces an image of the object observed, and this image is magnified by the eyepiece.... When astronomers point their telescopes up at the sky to see distant supernovae or quasars, they’re collecting light that’s traveled millions or even billions of light-years through space.
Want To Make A Giant Telescope Mirror? Here's How NPR
Printed in Reflections: June, 2003. Make your own Newtonian telescope mirror that is? Most people think it is such a daunting task that they never even consider it. But is it really that difficult? When I started out in this hobby back in the late 60’s (I’m showing my age here), most everyone... My Mirror Grinding Machine. For a long time I've wanted to build a machine for grinding telescope mirrors. Dennis Rech's M-o-M designs finally inspired me to just get up and do it.

How To Build A Telescope Mirror
Despite your reflector telescope’s apparent complexity, it really consists of only three optical parts: the main mirror (often called the “primary mirror”), a small, flat mirror near the top of the tube (known as the “diagonal” or “secondary mirror”), and the magnifying eyepiece that you look into.
- Richard Berry has a book on telescope making (intro level), and then he co-wrote an advanced level book with David Kriege (of Obsession Telescopes fame). Armed with all this docu, and lots of patience, you can build a great scope.
- The laws of physics dictate that to pick out ever fainter objects from space and see them more sharply, we're going to need a bigger telescope. And that means we need massive mirrors.
- or larger telescopes with objective mirrors of up to 15" in diameter. Just remember that the tube of your Just remember that the tube of your telescope needs to be at least 1-1/2" wider than the diameter of the objective mirror.
- A mirror much larger than eight meters, made of a single piece of glass, would be too expensive and too hard to handle. Everyone involved in building giant telescopes agrees that the solution is
