Contents
The site has a sky in it, and this section is what that sky is about.
It is not wallpaper. Every star behind every page is at its real right ascension and declination, projected the way a planisphere projects them, and the wheel is set to the sidereal time on the reader's own clock. Point at a figure and it draws itself; stay with it and the thing it depicts surfaces, warms to gold, and becomes a link into the pages below.
Everything here is written for 40° north — central Ohio, where this site is — because a sky guide that will not say what latitude it means is a sky guide you cannot use. What is circumpolar, what never clears the trees, what month a figure stands highest: all of it is answered for that horizon and no other.
Sections
| Section | What is in it | Count |
|---|---|---|
| Constellations | One page per figure the site draws — the stars in it, how to find it, what it has meant, and what is worth a telescope | 28 |
Stars have no pages yet. The 193 the chart draws are the queued next step, and the boundary past that is the IAU's list of proper star names rather than a catalogue dump — a database question, not a page-writing one.
