Mercury 20/05/21

A waning crescent Mercury, with some barely discernible albedo features.Took a while to find in daylight hours, after I eventually found two stars for an accurate alignment of the scope.

 

Mercury was magnitude 0.69 with angular diameter of 8.65", and was 30.1% illuminated.

 

Nexstar Evolution 9.25 scope with 2x Barlow and ADC; ASI224MC camera with 610 nm filter.
