    That is really clever it makes one wonder why nobody thought of it before. Kudos!

    I assume it is your voice we hear on the video, good to hear a real voice from one of our members.

    As you said, you can always use the center of the rose for the AP and it doesn't have to be a whole degree of longitude, there is no reason the center verticle line has to be a meridian, it can have any longitude you want it to have. You can then draw your graticle to make it so. In fact, you don't need to draw the graticle at all since it is only there to make plotting easier with dividers. Navy flight navigators and pilots use a plotting board in such a way that you only plot the positions of interest and never draw in the longitude graticle.

    T-Plotter is a device that simplifies the plotting of celestial LOP's by eliminating the need to also draw the azimuth line. For more information, please see:

    A photograph of the "Basic" model (priced at US$29 per unit) is linked to this message.

    I set aside a small quantity of these to be sent free of charge to NavList members. If you are interested in obtaining this tool, please forward me your mailing address within the next few days and I'll send you one.

    Happy New Year to all!
