Lunar V & X on a High Res Mosaic, First Quarter | Aug 25th 2020

[MalVeauX]

Heya,

Today was a First Quarter phase, depending how close you are you can capture the Lunar V & X features (crater rims) illuminated at the terminator at different points through the phase. I had a sucker hole between clouds and was able to get it at 53% illumination. Visually it was fun to see as the "X" feature was floating in darkness at this illumination. The following disc is a high resolution mosaic, please feel free to see the full scale version on my Flickr or Astrobin. The resolution is 426 meters per pixel represented. Seeing was average, so I captured the data in 742nm IR wavelength.

Nice!

I was lucky quite a while ago to get the X and V the first time I learned about it and tried.

Not near the detail you managed.
