Here are the Saturn images from 28th April 2015...despite seeing that was
not first-class as shown by the stacked image of the diffraction rings
during collimation - we felt that the appearance of the onscreen star-test
images as they were would not allow finer tuning - we still suspect that
this is our best image of Saturn to date! The ASI174MM is proving itself to
be a superb planetary imaging camera, certainly for Saturn where we
currently employ frame-rates of 198fps for r&g & 141fps for b - with the
knowledge that we could have employed considerably faster fps!
