Hi there, I just spent hours trying to figure out how to use the sky coordinate system and I think I found a bug.
Take this star: .A. = sky coordinate for longitude in hours, minutes, seconds: 19° 23′ 56.41" Dec. = sky coordinate for latitude in degrees, arcminutes, arcseconds 48° 22′ 31.4" It's a bright orange Mag 7.93 star named KIC 010918449. I adopted it [0]. You can look it up in Google Maps, sky mode, by searching for "19:23:56.41, 48:22:31.4". The corresponding link is: http://maps.google.com/sky/#latitude=48.375388&longitude=110.985042&zoom=13&Spitzer=0.00&ChandraXO=0.00&Galex=0.00&IRAS=0.00&WMAP=0.00&Cassini=0.00&slide=1&mI=-1&oI=-1 The link contains decimal coordinates, which can be derived from the original coordinates using the instructions here: http://code.google.com/apis/kml/documentation/kmlsky.html "longitude" = (hour + minute/60 + second/3600)*15 − 180 However, when I use these coordinates with the Maps API Javascript, I'm sent to the wrong place. map.setCenter(new GLatLng(48.3753888888889, 110.985041666667), 13); map.setMapType(G_SKY_VISIBLE_MAP); var point = new GLatLng(48.3753888888889, 110.985041666667); After I zoomed out far enough, I noticed that I was on the other site of the galaxy, so I tried adding a minus to "longitude". var point = new GLatLng(48.3753888888889, -110.985041666667); That worked.
