This image was taken with a Canon 60D with a Vivitar series1 70 - 210 M42 mount, a 2x tele-coverter screwed into a 3x tele-converter, making 5 x the 210 and a farther 1.6 for the crop sensor making this a 1680mm focal length.
This was an experiment, the Native hen shot shows a very shallow depth of field, I will have to make sure my aperture is closed down and the second one I think I changed it to F22, giving a better image. Next time it is a cloudless night I shall try it with a moon shot but the way the weather is over here it might be some time.
