    Dear Greg,

    Thanks for your shooting report and drawing.

    What do "Hs" and "Hc" stand for ?

    "Raw" instrument reading ? Which I suspect for "Hs"

    Corrected for Bulb Error ? (Which I suspect for "Hc" vs. "Hs") hence we would still need to correct for atmospheric refraction and parallax,

    Corrected for Bulb Error and atmospheric refraction ? Hence we would still need to correct for parallax ...

    Corrected for everything including parallax (i.e. geocentric value) ?

    Thanks in advance.

    Expecting to shoot all of them on the Western Coast of France shortly, maybe when Lady Moon is back in the night sky ...

    Very Best Regards
