    Bruce Stark lurks on this list as well!  The mailing list had a good exchange about lunars a few months ago.
    The sun is finally showing itself here in the Seattle area; lunars will be a fun summertime activity here!
    PS - Welcome to the list!

    You are a man after my own thinking.
    I am new to this forum so this is my first posting.
    I have used my sextant to observe numerous solar eclipses. It is the best thing for this purpose. I have never tried to take a photo though. Next time around. You must have a steady hand.
    Here's another use for a sextant: I used one of my aircraft bubble sextants several years ago to take a round of shots of comet Hale-Bopp. I got the emphermis data from the astronomy department of a Canadian university. Didn't do too badly at that. Took four shots and averaged them out. I was able to fix my position to within 2 nautical miles.
    But if you really want a good excuse to use your sextant, I suggest that you take up lunars. They are a hoot, and you will get some serious sextant practice under your belt in the process. In 1999, a fellow by the name of Bruce Stark published a simplified set of tables for clearing the lunar distance. Mr. Stark spent over 20 years developing them. I in turn, spent a few months in mastering them by constantly practicing out on my deck, late into the evenings. Then came the sight reduction...
    If you like sextants, you'll love lunars. I believe that these tables are available from Celestaire in Wichita, Kansas. I highly recommend them.

    Last night we had a partial solar eclipse here in the Seattle Washington area.  I wanted to look at the eclipse so I used my Tamaya Jupiter sextant with a 7X scope and a dark gray filter and a green filter.  Worked great!  I had all of my family look through the sextant to view the eclipse.  I then had the idea to put my Kodak digital camera up to the sextant eyepiece and I took a couple of decent photos! 
    Any excuse to use my sextants... ;-)
