Pic of the one and only , in Australia that is, taken at Temora NSW

Nikon D70 Sigma 50-500. 1/250, handheld, and before you ask ,no
all my shots did not turn out sharp, i will be upping the shutter
speed in future or using a monopod,in order to increas my succes rate,
more to follow.

apart from the oversharpening... it's a good shot...

cheers

it doesn't look oversharpened to me
the problem with increasing the shutter speed is that the propellors will freeze. i think a monopod would be a great help for this type of shooting, plus shooting when the aircraft is closer, eg on short final or landing.
