There are four instruments in the Celestron StarSense Explorer range: an 80mm refractor, a 114mm reflector, the 102mm refractor under test and a 130mm reflector. All these instruments are standard members of the Celestron range and are available in other mounting packages. In this range, the 80mm and 114mm are supplied on lighter weight mountings, while the 102mm and 130mm have the same heavier mounting. The alt-azimuth mounting means you can move the instrument around two axes – up and down and from side to side. This is the simplest form of mounting, and is particularly suitable for a beginner. The alternative equatorial mounting, with one of its axes tilted at the same angle as your latitude, not only confuses many beginners, but has the drawback that it involves an overhanging load usually balanced with a counterweight, reducing the portability.
