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
