The sky was clear at lunchtime again today, so I decided to make the most of the oppo of seeing the moon and try a little experiment. I used my new Redsnapper tripod to mount first the scopes in turn and took a series of shots to show the different scale at various focal lengths using the 450d. Including the 55-250, this ranged from 250mm to 1200mm.
Using the Konus Vista
The C80ED
The Vista again
And finally back to the C80ED
The only variation on the scopes was the fitting of a 2xTC to increase the focal length. I had been hoping to check and see how the TC really compared for IQ, but there wasn't enough contrast to work it out.
