    Default New double star and binary star site

    Hi,

    That's really cool! But please consider using conventional units for
    right ascension (hours). Using degrees makes it unnecessarily difficult
    to enter the coordinates into software and web sites that adhere to the
    normal astronomical conventions.

    Thanks,
    Greg

    I take your point but since SDSS uses decimal degrees for all their
    work so do I when I use their material.

    So you expect anyone reading your site to do the necessary conversions
    for themselves? I'm not speaking of the SDSS data itself, but for the
    snippets of data you display on your site for specific stars. I would
    think those could be in the conventional units (not that I don't care if
    it's decimals or not).

    At the very least you should state clearly that the units of RA are not
    what most people expect. I entered the first star on your list and it
    was not apparent why I could not find it until I looked further down and
    saw "celestial longitudes" > 24. Come to think of it I don't think it's
    even proper to call them Right Ascension if not in specified hours.

    Thanks for your consideration.

    Greg

    That should read "note that I don't care if it's decimals or not)."

    When I was a school I was taught the conventional units of length
    were:

    12 inches = 1 foot
    3 feet = 1 yard
    22 yards = 1 chain
    10 chains = 1 furlong
    8 furlongs = 1 mile

    Five different bases to work with!

    Now people use Km and m - conventions change.

    Actually the name of the star tells you where it is
    J011251.46+141957.6 = 01h 12m 51.46s +14d 19m 57.6s

    I should also have pointed out that the name of the star gives a clear
    indication of the position.

    J011251.46+141957.6 = 01h 12m 51.46s +14d 19m 57.6s
