Celestron Serial-to-USB Adapter Cable 18775

This adapter allows you to connect your Celestron computerized telescope to your PC through a high speed USB port, rather than through a slower serial port. This is particularly useful with the laptop computers that most astronomers use to control their scopes in the field, as these portable computers now rarely include a DB-9 or DB-25 serial port.

The USB adapter includes a short (24") cable with a DB-9 connector at one end and a USB connector at the other. The USB end of this cable plugs into your computer. The DB-9 end of the cable mates with the DB-9 connector on the cable supplied with most Celestron computerized scopes to connect the scope to a computer. 

Celestron sources these cables from a third-party manufacturer (TRENDnet part #TU-S9), so the packaging does not have a Celestron logo on it, only a label on the bottom with the Celestron part number (#18775) and the legend "cable, USB to RS232." The cable supplied by Celestron is as shown in packaging similar to the images on this page, although the packaging color may vary.
