We went out last evening around 21:00 edt and attempted to get some images of the Werner lunar X. This is from a Canon T7i on a tripod with a 300mm f5.6 zoom lens. Focus is not sharp at all (used live view and max zoominess)

So.. neither the 500mm mirror lens nor the 75-300mm lens do the feature justice.

Was going to use the telescope… but… even though the black flies majorly diminished in yesterdays heat.. were replaced by locusts of mosquitos. swarming was too kind a word out back in the field. Yet Kim inside the SCGO reported very few of any flying insectoids.
