Each axis is cropped by about 35%, with a resulting final resolution of 1904x1266. Do the math and you get a 1200mm equivalent focal length in full-frame format before digitally cropping. Sadly, the lens is not mine.
Whoa... How much did you zoom in? When was that taken? The moon is full tonight. Do you think you could make out some detail of other planets with that setup?
As he mentions in the post you just quoted, he is zoomed in to 400mm using a 2X teleconverter, giving him a focal length of 800mm. Add in the 1.5X crop factor on Nikon DX format, 800 X 1.5 = 1200mm. Nice.

I don't think one really needs a tripod badly. A full moon is actually very bright.
His lens alone, without the TC, weighs in at 10.2 lbs.
At such a long focal length, slow aperture and huge lens, the shake produced by hand holding wouldn't make for a sharp photo.
And I thought my 500mm (750mm w/crop factor) shot of the moon was close.
