    New utility by Jeff Conrad: Sun/Moon calculator

    Another tool I believe not yet mentioned is Sun Clock. It's free and has worked well for me.

    what I've done is use an image of a map as background for an Excel graph then from the data from Conrad's calculator, overlay lines in the right direction (e.g. direction of sunset). It can be automated with excels functions:
    - with the sun/moon calculator create a table with resulting data spanning a priod of interest (first thought: 1 year!!)
    - import the table in excel
    - create a function that searces the table for a date you type and retrieves relevant data
    - work through the necessary sines, cosines and tangents an have excel plot lines in the wanted directions over the map

    not 3D but I hope it will help me choose the right spot where to get moon reflections on the Po river.

    Thanks, but on-line calculators are good only before you leave the house. When you need it most, you're on the road, or in the middle of a beautiful nowhere. What good is a laptop with a browser then? A stand alone app is what's really needed.

    Jeffrey, maybe I am wrong, but I think that Jeff wouldn't mind if you copied the four files that make up the Sun/Moon calculator to your laptop for personal use. If you do so the calculator will run as a stand-alone.

    for personal use.


    Not a problem. If you have a Wintel machine, though, you also might want
    to consider the other two programs that I mentioned--they'll run a lot
    faster. Since Ephemeris is free, why not? And Heavenly Opportunity might
    be worth it just for the database.

    I don't mean to suggest that other similar programs aren't good. However,
    like my calculator, Ephemeris and Heavenly Opportunity were written by
    photographers primarily for photographers, so they provide azimuths as well
    as rise and set times. Many other almanac programs don't do this.

    If you have a Mac, I don't know what to recommend, although that certainly
    doesn't mean that nothing is available--it's just that finding it hasn't
    been my top priority.

    Great calculator. I've been looking for an app like this for calculating the lunar times. You mentioned that you don't mind if we copied the 4 files to our laptops, where can I get those 4 files?

    If not the files can I get the formulas used? I could easily write a program using VB to have a stand alone executable but I don't want to have to figure out the formulas used in the calculations.

    Thanks,
    Leland
