January 31, 2013 #131 - Cartes du Ciel

Cartes du Ciel has improved over the last year and I have just  upgraded to beta version 3.7-svn2418. Patrick Chevalley continues to produce, amazing free sky charting software. By downloading the UCAC4 data base and installing the files in the CAT folder you can produce charts  to magnitude 16. There are 4 files in this set: North, Equator, South, and Index. With other available files you can even have charts reaching magnitude 20. These file are enormous though, but you can tailor them to your needs. His site gives clear instructions on what you need to download and how to use this data. Below is an example of the mag. 16 chart.

A control program can be linked to this charting software that also functions well and can be set up to control many GOTO scopes. It goes by the name of RTGUI v9.2. (Real Time GUI + SKY CHART) by Robert Sheaffer.

Both application are well behaved, provide tons of features, and can be downloaded for free.
