This morning gave a really excellent view of Jupiter in the Dobsonian. The sky was lightening constantly as I watched and the reduction in contrast against the sky I believe enhanced considerably the view and removed any diffraction spiking that might have intruded. Venus as a semi-crecent and Sirius were also prominent.
