d. 1C Catalog
This is the complete 1C catalog of a variety of objects that the standard NGC catalog missed.
e. GCVS Catalog
This is a complete catalog of variable stars (shown at the bottom of this page).
Variable stars from the GCVS are entered using a six digit number. The first two digits, refer to the constellation where the variable star is located and is listed in the table below. The next four digits are assigned sequentially within each constellation according to the standard sequence of
Therefore, the first star in the constellation of Virgo would be entered as: 860001.
f. Star Catalog
The STAR catalog contains the 250 brightest stars (STAR 1 through STAR 250), 100 interesting double stars (STAR 251 through STAR 350), plus Sigma Octantis, the southern pole star (STAR 351).
g. M (Messier) Catalog
The M catalog has been the benchmark
h. Planet Catalog
The LX200 calculates the orbital positions of the eight major planets for the current calendar date. To access a planet, use the STAR key and enter the appropriate number as indicated below: (NOTE: 903 is the Moon.)
