    Greg:

    The mistakes you mentioned are certainly a possibility, however in this case, I do not think that they apply. I take particular care respecting setting up the 2102-D, making sure the north side of the star base is facing me, and that the 35D template is similarly oriented. I'm also aware of the Nautical Almanac times being Standard Time, and have added one hour, as you mentioned. Alas, correcting time for the 2 D farther west is something I've overlooked.

    Unfortunately, we returned to Pittsburgh on Sunday, where we are, once again ensconced in such strange lands as lack a sea horizon. Actually, what with light spill from office buildings, about all that one can do around here is sun shots, possibly moon shots too, during the daytime.

    Interestingly, going out into the parking area at our apartment complex, using an artificial horizon, when I shoot the sun in the AM, and later in the PM, my estimated positions are usually well within 5 NM of GPS coordinates, and as stated earlier, at the beach, I got some three body fixes inside 3 NM of GPS coordinates.

    Thanks for your input, as it will prove useful when we next get to the coast.

    Alan
