    An excellent idea for outreach Dave, I'm just sorry that the weather didn't cooperate.

    "According to the report..."The objective was originally mounted in what is believed to have been a wooden tube, complete with a dew-cap and a 4.4 cm (1.7 in.) aperture fll1.7 finder. The tube was supported by a clock-driven German equatorial mounting on a brick and cast iron pier, and the drive clock was regulated by a Bond spring governor. The telescope was supplied with seven different eyepieces and a filar micrometer (Soley, 1876). In an old USNA report dating to 1869, Phythian noted that the telescope was" ... one of the best in the state ... ", but these laudatory comments need to be taken in context given that there were very few 'competitors' in Maryland
    at that time with which to compare it."
    Thank your the link describing the history of this Clark made Fraunhofer design refractor! I have no doubt that it is much more reliable than the rumor I related in post #7. I had heard various accounts from a would be restorer of the telescope (whose proposal was not accepted) and from staff at USNA. It is interesting to me how much the account here differs from what I had heard. Perhaps there was a lot of simplification since the folks I had heard things from were oversimplifying and cautious since they were aware I knew "the other side".

    I am reminded of the children's game of telephone. Thanks. I learned something. Next time I meet one of these folks for lunch I think some gentle teasing is called for.

    Very nice outing in spite of the sky conditions, Dave.
    As I have said before, I would love to visit there.

    I was the one who mentioned celestial navigation at the academy a few weeks ago. Thank you for asking them about it.
    My son is presently flying off of LHD-8 and on the ships facebook page the Capt. posted a photo of one of the sailors taking a local noon sighting. I think they do it just to keep in practice in case they "really" need it. :-)

    Again, thank you for posting the details of your outing.
    Clear skies!

    Bummer about the clouds and weather, but 70 is a very nice turnout and you have managed to show them a few things. Well done!
