D850 DSLR Moon imaging

Posted: 23 October 2020

Thursday, 22 October 2020, was cloudy with some smoke from California and Arizona wildfires still visible. Rain is in the forecast for Sunday so maybe the atmosphere will finally get a cleansing.

As I recently mentioned I had decided to permanently provide electricity to the Meade Stella Wi-Fi Adapter whose battery would no longer charge. Thursday morning I relocated its power cord to a permanent position. Now I just flip a switch and power it on to control the LX600 telescope from my iPhone using Wi-Fi.

Clouds (and smoke and wind) increased Thursday afternoon, but quickly decreased as sunset approached.
