Another recording, from the 11th. The morning sky was hazy with high
altitude clouds, but seeing was quite good. There was a constant
tendency for dew and I had to clean the corrector plate several
times.The clouds/haze diminished contrast and lengthen the required
exposure though, but some markings in the UV could be recorded. They
look distinct, very well defined narrow streams.
