The Moon tonight - 2 images attached

[William Bottaci]

Tonight's moon.
  Phase    57.04% (7d 7h)
  Altitude    52.5º
  Diameter    31º 40'
  Distance    377,299 km (29.57 Earth diameters)

Canon R7 with RF 100-500mm L IS lens (set to 500mm, f/8, 1/80 sec, ISO 160), hand-held stabilised.

A provisionally processed single image. My workflow for this image and the Moon in general (is not good enough to be a secret :)-

First expose so that the brightest regions, near limb, are close to but not quite overexposed - use the camera histogram, even better if it features an over/under exposure clipping indicator.

 - Rotate to upright;
 - Gradient, colour burn: 30%, from limb to half way to centre only, various places along limb - this is to ameliorate the limb brightness;
 - Shadows and Highlights - again evens out the exposure, because the terminator regions tend to be underexposed and the limb overexposed, and for this reason using Levels is not appropriate;
 - Colour saturation, increase to not quite overdone - the Moon has subtle colour;
 - Sharpening, minimal.

The same image prior to processing is attached to compare.

The yellow coloration is volcanic glass beads, orange tints are areas poor in iron, green tints are rich in olivine and blueish tints rich in titanium. Two weeks ago the other half of the Moon shows a lot more colour.
The floor of Ptolemaeus, slightly below centre on the terminator, is just seeing sunrise. An hour and a half earlier it was in darkness, as were parts of the far rim.

Thank you for looking, William

Good morning William,

Two excellent images.

The detail in the first image is superb.

The Terminator region on both images enlarge very well.

A good evenings work.

Martin

Hello Marlène, you're welcome; glad to oblige. Rotten weather lately, though last night was good, but then it was close to Full Moon and I had to travel.
William
