I wonder if anyone can help? I want to produce a basic planetarium app for iPad
that shows the appearance of the Night Sky anywhere on earth.
I believe I need:
A program to convert RA and Dec to Alt-azimuth co-ordinates.
A list of stars, plus details about how to add “constellation lines” between
selected bright stars.
A way of incorporating the Milky Way as a vector file.
Would be grateful for any help; am happy to pay for programs, lists etc.
And on a different subject, I would like to enter a sundial in the Italian
Astronomers’ International contest for sundial makers, but cannot find the form
to fill in. Can someone supply a PDF or web address?
Thanks,
