Jones Carpal Tunnel Reged: 07/02/06 Posts: 1572 Loc: Fort Worth TX Pretty crescent Moon, good seeing this evening       #2108595 - 01/09/08 08:13 PM Attachment (33 downloads) Edit   Reply   Quote Quick Reply   This was the sharpest of several shots I got this evening, using a Takahashi TOA-130S and Canon XTi. The seeing was surprisingly sharp given how low the crescent was. I had to resize the picture down to the CN 800 pixel width requirement, and there's actually much more detail available. Just some gamma adjustment and a touch of unsharp masking, that's all that was needed.

The longer exposure is bringing out the atmospheric dispersion in the crescent and blurring out the turbulence some, reducing the resolution. Notice the star to the right.

Can that be done in Paint Shop Pro or PhotoShop? Can you point to some good websites or references? It's more than just cut/paste/blend, isn't it?
