Tonight's Moon

One of the things I have spent some time thinking about was how to use

the focal length multiplier effect of a digital body to my advantage.

I had taken a few images of the moon previously with my film body and

a 400mm lens with a 1.4 converter just to see what that did for me and

the answer was not much. With a new Canon 20D I tried the same

experiment tonight and this time stacked an additional 2x tele on top

of the 1.4 tele. The major problem of this setup is shutter speed,

working at an effective focal length of 1792mm motion blur becomes a

real problem and at this magnification you can actually track its

movement in the viewfinder. The shutter speed was 0.5 sec and a 100%

magnification reveals significant motion blur. Even so, I was pretty

pleased with the result after two passes with the sharpening tool in

CS2.

Last month I took a photo of the moon with a Coolpix 995, placed the lens directly onto the eyepiece of a 1500mm astro telescope, it was tracking the moon at the time, was pleased with the shot, but yours is much better!

wonderful shot...very well detailed...and lovely thing sharing with us...thank u
