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 variable-star designations
(R, S, ...).
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 deep-sky catalog for
years. Recently expanded to 110 objects, the M (Messier) catalog
contains most of the best deep-sky objects.

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.)
