Hello to all,
At last ... years of patience just rewarded !
I could shoot Mercury Lunars from my favorite nearby Island 2 mornings in a row earlier this week.
Mercury was very faint, especially on the second day, nonetheless sufficiently visible.
Lucky me since this morning, it is quite foggy there.
Here are the Data:
For both Lunars, Height of Eye 16ft, Temp 8°C, QFE/QNH 1008 mb, Approximate position N46°30' W002°30'

Near-Limb Moon distance to Mercury corrected for Instrument error 32°33.0'
Mercury Altitude corrected for only Instrument error 3°13'
Moon Lower Limb Altitude corrected for only Instrument error 21°57'
