The astrometric (positional) and photometric info utilized by the software program was once acquired from the UCAC4 catalogue.

Over 3,500 asterisms are incorporated during this assortment. a few are certainly extra visually appealing than others yet anyone of them will make an attractive diversion from the ceaselessly recycled gadgets that substitute courses proceed to list!
