Mercury 2019: A very complicated camera, and not used telescope since 2012; Fading vision, inadequate glasses, and telescope position inconvenient resulted in only a few focussed pics. The shadow visible only after viewing on computer. Venus 2012: T-90 film scanned and enhanced (exposure increased and max. sharpness [Mac. preview]) The previous use of the Celestron C-8! Notice I had trouble focussing then, also.
