A 13mm Nagler brought out the faint mottling. M100 Large face on view, with stellar core and wide spiral arms. Best viewed in 40mm eyepiece. Very large spiral arms and bright core. Edge on galaxy with bright core.

Dust lane easily visible and distinct. I refer to the excellent images in his April Moondark as well as the images he showed us in the overhead transparencies tonight. Doug also showed images of the moon Io tranisting Jupiter and later the shadow of Io from the same transit. In another series, Doug caught the shadows of a double transit of Ganymede and Europa. Then as neighbors gathered, Doug learned the value of STV monitor as a display medium for demonstrations.
