Well the weather has'nt been the best this year for astronomy.I had a very small chance to test my Canon 50D and 17-55 F 2.8 lens,piggy back on a visiting astronomers' telescope about 6 weeks ago.
It was only a basic test,yes you can see the bit of his telescope in the frame,I planned to do a better shot the following night,but it was cloudy
Its 400 sec iso 500 17mm no guiding,no ICNR,just a basic test shot,
Hope you enjoy viewing,regards Chris
