Processing Challenge

Posted By Alan Friedman
Hi -

Just returned from a vacation in New Hampshire with my family, a 4" telescope, no camera and no internet! Lots of great images to look through here from the past two weeks.

I couldn't resist throwing my .02 into this challenge - thanks for sharing these lovely files, Chris.

best,
Alan

Hi Wes -

I like your recent images very much - they all display excellent processing and discipline to work within the limits of the imaging session. Thanks for sharing them.

Big south pole!

Hi Mike - Very Big and very Beautiful. I wonder if you are applying unsharp mask differently to the MAP regions? If so, it might be preferable to combine these regions and process the image as a whole to avoid the noticeable differences in sharpness across the field?

Rupes Recta

Posted By Alan Friedman
Hi Mike -

This and your new Plato region image are both excellent!

The straight wall is such a popular feature - I wonder why it didn't merit a more unique name. I've thought a good moniker for the region might be "Birt and Ernie" - what do you think?

Lacus Mortis Lake of Death

Posted By Alan Friedman
Hi Wes -

Very beautiful view of this lakebed in deep shadow. It is so hard to handle these images without posterization in the deep-gray/black areas - a higher sun angle is much more forgiving. I think this one came out very well.
