Feb 3 and July 14
Archive for July 2006
Hercules and Atlas (Hercules is on the left) First Quarter (February 3, 2006 9:44pm) and Third Quarter (July 14, 2006. just past midnight).
Deslandres is the large walled plain in the upper part of the image. The only fancy processing was to expand image in registax, as the telescope drifted a bit (to make a much better picture, actually.)
At the right of the Appenines mountain range there is a black shadow that looks like an open parenthesis that fell over.
That’s the Hadley Delta where Apollo 15 landed and first used a lunar rover.
This is an exposure of 340 frames drizzled .80 x 3, and after processing in photoshop, the dimensions were reduced by half. Jpeg quality is 100%. Usually I post at 50%.
I tried extreme drizzling: pixel size 50 percent, image size x3. Here is an image of the moon from Nectaris south.
The edge of the image gets noisy where there is not as much contribution from the frames, so I cut that off. The result from registax is extremely blocky; gaussian blur and unsharp mask work there, much like removing the moire from a scanned halftone.
