Hi Duncan,
Update: At the Full Moon and Half Moon it appeared spot on. The percentage illuminated amount just seems different by up to 8% or so in-between compared to various other sources. I’m very happy to put it on my site, as in my opinion it looks the best. Also, most importantly, the lunar image is always a close match to official sources and when I look up in the air ?? I’ll go give it a nice rating now.
Cheers,
Luna
