Hi all,

Here is my first image of this rille taken on November 11, 2006.
Meade 8" LX90 SCT @ f/25, DMK 21AF04 @ 30fps, 400/2250 frames.

Thanks,
Ed Roach

Hi Ed -

You've captured and processed excellent detail in this image!

As with many pictures taken at a low sun angle, it carries the processing challenge brought about by high contrast between shadows and sunlight. Some regions (ie: the major craters in dark shadow) pick up processing artifacts quickly while the areas in the mid tonal range can handle much more. Kind of like cooking a turkey - it is very difficult to roast a whole bird and come up with both white meat and dark meat perfectly done.

Photoshop selection tools can help by allowing you to process different areas of the image selectively. I've never processed an image in Registax - would be interesting to hear how others handle this challenge in their workflow.

best wishes-
Alan

Great shot Ed! That shift in the rille is very interesting.

Excellent image and detail Ed! Thanks for sharing it!
