StarChart 2.0 for Newton

StarChart for Newton 130	StarChart for Newton 2x00

StarChart 2.0 for Newton is an astronomic star chart, which displays stars, constellations and the planets for any time and place. It is based in main parts on StarChart 1.0 by Shigekazu Kase.

Requirements

There are two versions of StarChart available:
StarChart for Newton 130 is intended for a Newton 130.
StarChart for Newton 2x00 is intended for a Newton 2000 and Newton 2100.
Both versions might work on an eMate, if you have any experience with it, please email me.

Accuracy

The algorithms for calculation the planetary positions are accurat with an error of no more then 1-2 arcminutes for the 20th and 21st century. But in this release not all the nesserary algorithms are implemented, so at present a much bigger error might result.

Known bugs

• While daylight saving time, the time is one hour wrong. I do not know, how to get the right GMT. It is only possible to get the difference to GMT without daylight saving time. So, if you need a correct display, please set the time to winter time. I do not know, whether it will be fixed in the next release, or not.
• The positions of the planets are not very accurat. That's because not all algorithms for computing the positions are implemented. Will be fixed in one of the next releases.
• some other, minor bugs

To Do

• more accurat positions of the planets
• more infos for the planets (e.g. Decl. and RA, Long. and Lat.)
• abbility to display abbreviations instead of the full names (especially for the constellations)
