Atomic Clock for Meade ETX-Autostar

The Atomic Clock that Sets Itself and synchronize with U.S. Atomic Clock! Built-in radio receiver automatically synchronizes with U.S. atomic clock to set its time, day and date. It adjusts easily to the four U.S. time zones with he press of on button, and automatically switches to Daylight saving time. Using is internal antenna it activates daily to seek the time signal from the U.S. Atomic clock, the most accurate timepiece in the world, operate by the U.S. Commerce Department in Boulder, CO.

Why is the exact time important for precision Autostar GOTO?
There are 1440 (24 x 60) minutes in a day while the earth rotates 360 degree. That means the earth rotates 0.25 degree each minute. The field of view of a 26mm eyepiece on ETX-90EC is 1.1 degrees. If the telescope is not tracking the target object, it will go out of view in 4.4 (1.1/0.25) minutes..Every one minutes error in the Autostar time, the target object would be off by seconds or 0.25 degree. If the time is in error by 4 minutes and that is 1 degree. There shouldn’t be any doubt that if you do not set the Autostar time to the exact time, the telescope is not going to point to the exact direction of your target object either. Remember, half a degree here, quarter a degree there, you’ll miss the target. Precision time is one of the factor that affects Autostar GOTO and is easily available. You need an atomic clock as the precision time source!
