moon, calculations and web pages
Hello,
I'm an amateur photographer. I was interested in the moon, moonrise/moonset, position in the sky and phases. So I picked up a copy of "Practical Astronomy with your Calculator", and found that this wasn't so easy. Two days later I've converted most of the time and co-ordinate systems to javascript and can find out where the moon is and so much more. This is not highly accurate but most should be accurate to within a few seconds and some to a few minutes. I'll write a web page for this shortly and was wondering what if any of this would be of interest. Is anyone interested in ecliptic-equatorial-horizon conversions? Degrees/minutes/seconds or fractional degrees? What about local-GMT-GST-LST? The reverse? Moonrise, moonset and phases at any given time? In days, degrees or fraction (for phase)? Bright limb angles? Planetary and solar positions? A few stars? which? Option to plug in right ascension and declination and see where? Sunrise/sunset? All these would be done client side, no waiting for a web page to come back. I was thinking of a 180 horizon view with a choice of direction. Click on an object and it would give co-ordinates. Would work in IE5+, NS7 or Opera 7 although the calculations work in NS4. Any feedback before I glop this together would be helpful. I don't even own a telescope! Cheers, Jeff |
