This was part of a 1 hour capture session which resulted in 25 SER videos totalling 50Gb. Here is a typical capture in progress from the session:

Filters tried were IR685, UV/IR-cut /L, Wratten #25 red including combinations. With the moon crossing the meridian, the UV/IR & #25 red seemed the best combination for handling the brightness and giving good contrast.

Thanks. 2 years of struggle to get to producing that standard of image consistently.

You picked a perfect few moments on the terminator with that one and it appears very sharp. Thanks for providing the details. I have tried but have yet to get an image worth posting of lunar detail. Another go tonight possibly.

Moon is nearly 100% tonight so difficult to pick out features. What I did was use Virtual Moon Atlas and the Ephemeris tab (top right). I know from experience that when Copernicus is visible, near the terminator and not burnt out then Mare Imbrium will be illuminated so as to make a good capture.

You will still need to work out which filters (or combination of filters) are effective at reducing the brightness.

There will be some good illumination with shadows towards the end of the week but it means early morning work.
