Zoom

Now, the template is using distance for calculating the zoom, but isn't a good method. I suppose a better way could be based in apparent magnitude, but I don't find a good formula. Telescopi (talk) 18:57, 25 March 2009 (UTC)[reply]

What is it supposed to do? Why would you want apparent magnitude? I understand lightyears, since it's a triordinate, along with right ascension and declination. What do you mean by zoom? In any case, the distance parameter, whether it is used or not, should remain for future options, if you can slice the sky into redshift co-moving distance planes of view / depth coplanar views. If you mean how large a patch of sky should be shown, that would be apparent size usually given in degrees, arcminutes or arcseconds. Probably a number of arcseconds in diameter should be given, and then the template supplies a skyview 10x that size (in minimum W or H, whichever is smaller). 76.66.193.69 (talk) 06:47, 26 March 2009 (UTC)[reply]
I suppose you are right. Lightyears is now a few useful parameter, but it could be used in a 3D database, and then we shouldn't delete it. Yes, I meant "how large a patch of sky should be shown", and I suppose that apparent size should be a better parameter, but now we should find how to program it.

The difficulty would be with stars... since they are quite small (in angular size), so maybe a combination of distance and apparent size should give the view size, if it's a nearby small size, a larger patch of sky should be shown than if it is a distant small size (like a quasar) 76.66.193.69 (talk) 23:47, 26 March 2009 (UTC)[reply]
