Yes the latter shots are just going into 100% corps, so one pixel on screen is one pixel on the camera which is where the noise is coming from. Having to use 3 teleconverters to get the focal length doesn't help with softness/lack of detail and the quite high ISO is making the noise visible.

Here are some moon shots from a photog who always impresses me

At current prices we are looking at

Sigma 300-800mm f5.6 $8,700 or 7200
Sigma 2x TC $299 or 220
Sigma 1.4x TC $249 or 180
Canon XS/1000D $449 with kit lens 365 with kit lens

That's $9697 or 7965 not including the tripod.

Check out this setup though

All things considered I think it's an amazing shot. Each of those add on's cost you in sharpness, yet it still looks pretty damn good!!!!
