SkySafari utilizeaza  Hubble Guide Star Catalog cunoscut in mod normal ca GSC 1.1 ACT

"The Hubble Guide Star Catalog &#8211; Astrographic Catalog/Tycho (GSC-ACT) is an astronomical catalog. It contains the twenty million stars of the Hubble GSC, version 1.1, recalibrated using the U.S. Naval Observatory's ACT (Astrographic Catalog/Tycho). By 2009 it was considered obsolete, superseded by such catalogues as GSC-2.2, B1.0, A2.0, and especially UCAC-3."

respectiv

"The HST GSC contains nearly 19 million objects brighter than sixteenth magnitude, of which more than 15 million are classified as stars. They are organized into 9537 regions on the sky. "

DSO Planner utilizeaza UCAC 4
"The fourth United States Naval Observatory (USNO) CCD Astrograph Catalog, UCAC4 was released in August 2012 (double-sided DVD and CDS data center Vizier catalog I/322). It is the final release in this series and contains over 113 million objects; over 105 million of them with proper motions. UCAC4 is an updated version of UCAC3 with about the same number of stars also covering all-sky."

Am folosit Stelarium si Starry Night 6, le-am abandonat datorita erorilor de pozitionare.
Pe de alta parte Safari costa aproape 50 euroi......

Doar ca idee, nu vreau sa influentez pe nimeni.

Numai bine
