You certainly have better seeing that I get on a typical night. A lot more detail in this one than I could get. But the color is very different. I had a very blue center with a red ring. http://www.spacebanter.com/attachmen...tid=2208&stc=1 Not sure why the difference or which is more correct. I see it both ways on the net. Rick -- Correct domain name is arvig and it is net not com. Prefix is correct. Third character is a zero rather than a capital "Oh". |

that's a cool shot of exactly the sort of target I had in mind when I made
the Stinger.... i'd like to try that target with all my exotic filters... "glen youman" wrote in message ...

Using 2003 color data so I'm confident it is not G2V calibrated -
Color does need to be redone - original color data was obviously collected during some bad seeing.

Beautiful image. I only have an extremely poor version from 2001. Time for a
reshoot. Stefan "glen youman" schrieb im Newsbeitrag ...
