A simple command to convert calendar dates to julian dates. Quite useful in timing situations where you need elapsed time between dates. Also useful for astronomy applications.

This module implements the serial commands supported by the Celestron NexStar hand control (HC) and SkyWatcher/Orion SynScan HC. This applies to the Celestron: NexStar GPS, NexStar GPS-SA, NexStar iSeries, NexStar SE Series, NexStar GT, CPC, SLT, Advanced-VX, Advanced-GT, CGE, CGEM etc. SkyWatcher: EQ5, HEQ5, EQ6 (Pro), AZ-EQ5 GT, AZ-EQ6 GT, EQ8 etc. and the corresponding Orion mounts. Communication to the hand control is 9600 bits/sec, no parity and one stop bit via the RS-232 port on the base of the hand control. For extended example how to use this perl module look in to the distribution folder for nexstarctl.pl. This program is a complete console tool to control NexStar telesctopes based on NexStarCtl module. To control network based telescopes nexbridge must be used on the remote site. https://sourceforge.net/projects/nexbridge/
