Quarter Moon, that is.
I shot last qtr last month and first quarter this month. I tried to get to merge them in a panorama program but it would not work. This was as close as it would bring them, but kinda interesting anyway.

With all due respect, cause the exposures look good and sharp, but the mosaic looks, well--it looks like something found in the xerox machine the morning after the office Christmas Party.

Keep working on it Walter, the program you use undoubtedly has some adjustments to move one image in relation to another and blend overlap. This looks like the programs first cut, but I am sure that it is not easy for the program to figure out how they are supposed to go.

I have not mosaic'ed astro images but have with daylight stuff, and sometimes the programs nail it perfect but often you have to make a some fine adjustments.

Hi Walter -

Lunar libration makes it a hard mosaic project. I pieced it together to make a circle and remove the tush smile - but it looks pretty strange when compared to a lunar atlas.

cheers -
Alan

Here's another version Walt. Not nearly as nice as Alan's one and I chopped off the top and bottom as they were so awful. The reason for posting it up is that it was done almost automatically by some software called PTGui which you can get for a 30 day free trial online. I've seen it used recently to create a 170 piece mosaic of the mooon which was pretty amazing. This was my first go at using it and obviously with two curving halves that don't match very well it was a tough one to try it out on.

Regards, Tim
