About this image

Some good seeing and great transparency at the perfect time, with Venus at 19% phase on 24th.

Two sets of data one of 17mins and one of 13mins total are presented and compared with the WJ thermal map. This data was collected using the new ASI585MM camera which seems to be about 55% more sensitive than the Uranus-C at these wavelengths.

Settings were gain 300, 25msecs exp, f4.6, 444mm Dob. - other details on the image.
