Can You See the Green Cheese?

As you can see, once I get onto something, it’s really hard to get me off of it.  Out again tonight but this time did some playing around with different cameras, lenses and teleconverters.  This image here is right out of the camera, no crop or enlarging.  It was taken with a Nikon D300s which is a 1.5 crop sensor ( I’ll explain later) with a 600mm F4 VR lens and the new 2.0 teleconverter.  The end result is an image taken at 1800mm.  If you do the math it is 600mm x 2.0 (teleconverter) x 1.5 (D300s sensor size) = 1800mm.

Ok, so now here is the same moon, no tricks, shot with the same lens combination as above.  The only difference is it was shot with a Nikon D700, which is a full frame camera with a sensor the same size as the old 35mm film cameras.  That is what makes it different from the D300s above, larger sensor so a different field of view and the moon looks like it’s farther away.  600mm x 2.0 (teleconverter) x 1.0 (D700 sensor size) = 1200mm.
