On at 14 h, 48 min, 56 s, (UCT) on Nov 20th, I reduced a sight for Vega using HO 229 Marine Sight Reduction Tables Vol 4. Everthing work out fine, my LHA was 239 degrees and corrected Hc was 12 degs 05.4 min (which was vey close to my Ho). However, when I used HO 249 Vol 1 (Selected Stars) it did not work at all. I entered the table for LAT 49 degrees North with an LHA of 239 and got an Hc 59 degs 36 min. I can't figure out what I'm doing wrong!
