Welcome to the free planetarium program HNSKY for Windows. It is complete with the SAO, PPM, Tycho-2 star databases, up to date deepsky database containing 26000 objects , Realsky (r) images and access to the external GSC and USNO CDROM star catalogs. Telescope control using the universal ASCOM package, a Realsky viewer (incl. source) DDE controlled from HNSKY and a BMP/JPEG to FITS conversion utility.

The next program: "Hallo northern sky" or HNSKY is a planetarium program for windows. Have a try. It is free with 26000 deepsky objects and all stars to magnitude 12 and with the original GSC CD's, GSC-ACT or the USNO UCAC2 to magnitude 16. It displays all planets, the Moon, Sun, moons of Saturn, Jupiter, Mars, Uranus and Neptune and a few hundred asteroids and comets. It comes with 255 small DSS deepsky images which will blend in at the right size and orientation. It will run under Windows 95 or later. To install the program you start with the basic package or just put all the files in one directory and just run the main file HNSKY.EXE.

Updates:

The HNSKY.EXE file only HNSKY.EXE

The new 2008 DEEPSKY .HLP helpfile hns_deep.zip

The deep sky database contains 26000 deep sky objects based on SAC 7.2, Wolfgang Steinicke revised NGC & IC, Kent Wallace SEC (PN) database and many galaxies from LEDA. They are in the standard CSV format with a comma as separator, so they can be read/imported by many programs such as Excel. They contain the latest modern data and many corrections of the last years from sources such as www.ngcic.org

Here are some links and source codes for ephemerides calculation and some other interesting astronomy programs:

Excel table routine for correcting the position of stars and deepsky objects caused by the precession (the shift of the Earth axis and ecliptic), for example equinox B1950 to J2000. Implemented in Excel as a visual basic routine using the rigorous method, so the accuracy around the poles is optimum. Can be used to convert star/deepsky databases in Excel.
