    I am not a PHP guy, and I don't have the time to learn it to develop this, but
    I thing someone will soon pick up on it.

    Why not make a broader use of the data in Stellarium, and add a search tool
    for a star or galaxy which is an exact ligh-year distance from us, regarding a
    certain date
    Imagine a search box where you type in a date, and it identifies a star: The
    light from the star that you are seeing now, left the star on that date.
    You type in a date around 8.6 months ago, and it shows you Syrius. You type in
    your birthdate, and it shows you which star you are seeing now, with light
    from when you were born.

    Let me know what you think.

    Uhhhh, what's you plugin exactly again. I'm not sure I got what you saying. Do
    you want it to tell the magnitude of the star at a specific date? Or do you
    meen see the light it emitted a while ago, because you'd have to be 100,000
    years old (at least) to see ANY change in light or brightness. Can you please
    re-phrase the statement.

    It means that if you are 30 years old. What stars are 30 light years away.
    Show only those.

    Modifying star rendering is not something which could be done in a plugin -
    not without totally duplicating all the star rendering code in the plugin and
    turning off the original star rendering. Plugins don't reach into the draw
    functions of existing StelModules. I mention this implementation detail only
    to show that the change is not necessarily as simple as you imagine (although
    a distance filter wouldn't be difficult to implement).

    Moreover, many stars in Stellarium's catalogs don't have distance data. I
    suppose you could just assume those stars were at infinite distance for the
    purposes of deciding whether on not to render them.

    Having said all this, I don't feel that this feature idea is widely desired,
    and is not really congruent with the primary goal of the program - to create a
    realistic simulation of the sky. That is not to say there's no use for it, but
    I feel that for a change to the core code - especially something as
    performance critical as star rendering - a new feature must be more compelling
    than this.

    Feel free to create your own branch of the code and have a go at implementing
    it. Post to the pubdevel mailing list for pointers on how to go about doing
    that if you would like help.

    Also, a hint about open source projects: starting a feature request with a
    statement like, "I can't be bothered to spend the time on this myself, but
    maybe one of you could do it for me" is not a good way to get developers
    interested in helping you. To me it reads like "this idea isn't worth my
    precious time, but maybe you could spend your time on it". Not persuasive.

    Matthew

    P.S. PHP has nothing to do with Stellarium.

    Matthew - I'm having an awful time trying to ask a question about Stellarium.
    This is probably related to my elderhood. I sent you the following email a few
    days ago. Perhaps this is a better way to reach you.
    Matthew -

    Stellarium is wonderful! I'm switching to it from Cartes du Ciel for several
    reasons: flexibility, intuitive interface and large star data base.

    Three questions:

    I haven't been able to figure out how to copy (to the clipboard) the star
    information that appears in the upper left corner when a star is selected.

    A second question is why the catalog names of some stars are not reported as
    part of the star info.

    Finally, while reading through stellarium_user_guide-0.10.2-1.pdf, I found
    several typographical errors - as an example, here's the first one I came
    across with a quick review
    ..........................................

    3.1. TOUR CHAPTER 3. INTERFACE GUIDE

    3.1.5 Help Window

    Figure 3.4: The help window

    The Help window lists all Stellarium’s key-strokes. Not(SII!) that some
    features are only avail-
    able as key strokes, so it’s a good idea to have a browse of the information
    in this window.
    The About tab in this window will show licensing information, and a list of
    people who
    helped to produce the program.
    ..........................................
    Another one that caught my eye was "annular parallax".

    So the question is, would a list of such fluffs be useful to you, or is the
    document in such a state of development that it would only be a distraction?

    Sincerely,

    Herb, this or the mailing list is the correct way to reach someone; do not
    e-mail them directly. Also, you've responded to a conversation with content
    not related. Please start a new thread for that.

    Lastly,
    1- you can not copy data
    2- becuase it's simply not important
    3- yes, typo reports are helpful Please put them on the stellarium
    documentation launchpad sire.

    treaves - Thank you for your prompt reply. I tried to start a new thread, and
    received a message that I had to reply before I could. This seemed odd, but
    that's why I replied to a an unrelated thread.
    I'm sorry to hear that I cannot copy star data to the clipboard. It IS
    important to me for searches in VizieR. Cartes du Ciel allowed that function,
    but Stellarium has many advantages over Ciel. I will try to find out how to
    suggest the copy function after (hopefully) starting a new thread to explore
    the idea with others.
