Summed up a great Mercury Transit...

[TakMan]

Lost the close of the transit due to encroaching cloud (after a fantastic day of public outreach with a selection of scopes with White Light, Quark Chromo, Herschel Wedge, PST)...

 

 

Looked up around 6.40 and saw this instead - a Cirumzenithal arc!

 

Mercury - Nikon D3, TSA102s, 2x TV Powermate, Baader Herschel Wedge & Continuum Filter. Nova Hitch Mount Alt/az. Single RAW file processed in Lightroom
