Description

On the 30th August I had some gaps in the nearly constant cloud cover through which to image. My main objective for that evening was to try to add to my weekly cloud movement animation for Jupiter.

I did manage to grab some frames on Jupiter (yet to be processed) but the whole time the Moon was in the corner of my eye, calling to me. Seeing was good and that section of the sky at least was clear of clouds ... perhaps that explains why!

Whenever I image the Moon around this phase, I'm always drawn to Clavius. The arc of craters from Rutherfurd through Clavius D, C, N and J (almost in perfect decreasing size) is like art, and I enjoy imagining the series of events that lead its formation.

I think I've mentioned before that I find processing close-up images of the Moon the most challenging. With Jupiter and Saturn, processing brings out detail that I can't see through the eyepiece, so the data and image "lead the way" in terms of processing choices.

With the Moon, the views through the eyepiece are breathtaking in detail and dynamic range, and I just can't quite seem to produce an image that does those views justice.

I agonised way more than I should have with this data, trying to find processing settings that brought out the details available - the fine structure within Rutherfurd, for example - without introducing too many sharpening artefacts, especially towards the limb.

I have settled on the original and annotated version as the best compromise. Perhaps still a little over-sharpened for some tastes ... but not as heavy-handed as one of my earlier iterations! (See Rev D.)

I'm interested to hear opinions and suggestions!
