Astrolabe report (inventory number 35146) There are two different styles of script on this astrolabe.

The older is found on the tympans and the rete. It is a cruder script consisting entirely of square capitals, often created with a punch, and it uses older number shapes.

Encoder - a program for digital setting circles using a PC mouse

Introduction: The purpose of the Encoder program is to provide the amateur telescope builder an inexpensive means of interfacing between optical encoders on a telescope and a computer running some planetarium or sky position software. This program is free to all amateur telescope builders and is not intended for sale.

Making a Sturdy Wood Tripod - How To

I tried to make this article as comprehensive as possible, for the newbiest of beginners I could think of, so I made it out into paragraphs so you can figure out which parts you need to read and which you can skip. Most of the time I used metric measurements; remember that 25mm ~ 1”, and that anyway most measures I gave were for indicative purposes – you will adapt your dimensions to your particular needs.

Introduction I’ve been an astronomer all my life. I’ve been a member of the CN forums for a couple years, and seemingly every week, veteran observers and beginners alike come in and complain about how shaky their scope’s mount is.

The Andromeda Project. Arduino Bluetooth Digital Setting Circles for Telescope. I decided to build an Arduino digital setting circle for my mount because it's really hard to buy Tangent Instruments boxes cheaply, and the Argo Navis (the Lexus of telescope digital setting circles) is quite expensive.

Besides it seemed like a cool project. I used an Arduino Uno, which cost $32 (Singapore dollars) an Arduino Proto Shield ($5), as well as some headers ($2) I got an RJ-45 jack from Sim Lim Tower and soldered it to the Proto Shield. Obviously four (4) digital pins from the Arduino are needed to read the two encoder channels. Gary's Motorized Big Binocular Chair - by Gary Honis - Detailed Construction Procedure - Page 1 of 7.

Another DIY Parallelogram Binocular Mount. Another DIY Parallelogram Binocular Mount Submitted: Wednesday, 28th March 2007 by Dennis Simmons Introduction At the Queensland Astrofest in 2003 I stood mesmerised by the sight of a fellow astronomer, gliding effortlessly around the cosmos on his commercial, motorised, binocular chair, replete with GoTo capability.

The whole two-eyed, recline-in-comfort, “drive-me-there” observing experience looked simply awesome. At the time, I had with me my Vixen giant binocular (30x125), supported by the very nice Vixen Alt-Az fork mount, all fitted on a home made wooden tripod. My Comet Couch! - Article. My Comet Couch!

By Eugene Artemyeff ecart@surfbest.net I recently I purchased a new pair of Apogee 25x100's. Pleasing optical performance, great light gathering, but their ten pounds made my existing light weight parallelogram mount flex like a diving board once I put the required amount of counterweights on it.

He was a customs officer of the king and, because of his position, he was able to travel in England and Europe. He met people who owned books (that was not a very common thing then!) And he read as many books as he could get his hands on. He may have read, or at least skimmed thru, a great number of the books that were then in existence. In the Middle Ages very few people could read. Homepage | The Planetary Society. Science::.. The Astrophysical Journal Letters.
