Saturn and the Moon at 77mm Aperture and 152

[Derek Klepp]

I was going to use the Tamron 150- 600 with a 1.4 ext but the Canon 400mm with extenders was sharper I could not get the rings to focus wth the Tamron . An interesting experiment in lenses considering I only had 77mm of aperture.Well tried with the scope but next time I think i,ll just watch it through the dob .Saturn is enlarged in Second pic but still a single shot with the 60D +1.4 ext on the 152mm f5 scope.
Cheers Derek
