That is a stunning image, Wes - the clarity and definition of the shapes of the tiny craterlets is amazing. I'm glad you went back and finished it.

Nice work to keep up with the incredible shrinking planet. Early evening is often as good as early morning for that brief bit of steadiness, but it is usually a lot harder to sneak away from the family duties at 6pm than 6am. smile

Gassendi Monday night

Hi Steve -

It looks like very good detail is captured in your image but the horizontal linear pattern makes it difficult to discern. Assuming that it is real and not on my monitor only (I have been known to suffer from averted imagination!) I wonder if you've experienced it before and know where it is coming from. I have seen this appear in certain stacks made from my DMK camera video streams - usually, I think, when the gain has been set too high.

Hi Wes -

Beautiful image - this sun angle shows the central mountains and crater floor in great detail.

Hi Paul -

The color looks very accurate in this image. Which camera are you using these days?

A christmas Theophilus

Posted By Alan Friedman
Hi Anthony -

An excellent Theophilus. There is some noise/artifact visible only in the deepest shadows. If you have a copy of Photoshop, this is quite easy to deal with by selecting just these areas using the color range selection tool and then applying one of the noise reduction filters.
