So what use is a sidereal clock? It is a clock that is linked to the stars rather than the sun and reports the Right Ascension at your local zenith. It can be used to tell which stars are in the sky at any particular time.
The sidereal clock is built by replacing the electronics and the face in a normal clock and calibrating the rate with a computer linked to time references using the network time protocol (NTP). The calibration is designed to be accurate to about 1 part per million, or about half a minute per year, although variation in the crystal frequency over time will probably degrade this to about 1 part in 100,000 or about 1 second per day.
If you have any comments, suggestions or questions please email me. This is a new product and I am very interested in your suggests and questions. This helps me get the product right and make the web page information as useful as possible.
You can order the clock from my normal order page. Select clock from the left menu under Shopping.
I will be trying to keep a number of the clocks built and on the shelf. In stock clocks are indicated on the order pages. I have developed a production process that cycles weekly through any clock orders which are not in stock. So your clock will be produced in a week if it isn't on the shelf. Shipping takes between 4 and 14 days to arrive. On average allow about two to three weeks before your adapter will arrive.
