CDC includes the ability to control computerized GoTo telescope mounts, is ASCOM and INDI compliant, and supports the USNO's UCAC catalogs and ESA Gaia data,[citation needed] along with numerous other catalogs and utilities.[2]
The "red bulb" feature is useful when using software outside on a laptop on a dark night.[3]
According to the programmer, Patrick Chevalley, it was released as freeware because "I’d rather see amateurs spend their money for a new eyepiece than for astronomy software".[4]
Chevalley has also created a lunar atlas program, Virtual Moon Atlas, which is also free and open source software.[5]
