Following the excellent Lunars workshop given by Frank about a month ago I started shooting lunars, first by only shooting the afternoon sun-moon LD and comparing it with results from Frank's Lunar app. This worked quite well. Getting more confident I then also brought in the altitudes of moon and sun. (the quality of the mirror and its exact leveling seem to be my main accuracy-limiting factors)
A few days ago I got my best result until now: The Lunar app told me that my Lunar error was only 1.2' (including my altitudes sight results). With the workshop's Lunar Guidebook and notes I went through the pre-clearing and used the 3rd correction table method (which I find the easiest): The calculated GMT off-set for the cleared distance was just below 12 minutes.
But it can be neck- and hand-twisting. So, I am trying to shoot lunars in different positions. See attached.
