The names came from the lunar map included with May's Astronomy Now magazine.

Great work!

I find it interesting, though, that you and I took images of Copernicus at nearly the same time, the metadata is different. We were both using SharpCap 2.9, yet your exposure says "6.005" and my exposure says "0.05". I know that mine was 5 milliseconds, and I am quite certain that yours is 6.005 milliseconds. I was using an ASI120MC.

Robin, perhaps in the future you could add units to the exposure numbers?

Thanks,
Brian

Ah yes, each brand of camera has a natural unit for exposure (ms, s, microsecond for some) and that's what gets saved to the capture settings file. It would indeed be a good idea to add units!

cheers,

Robin
