Venus Image 2007/01/25(UT)
David Arditti (250mm Dall-Kirkham Cassegrain)|
In the last week I have been imaging Venus in daylight in UV and IR in the
The disk is about 11" and culminating altitude 23o, though these images were all
taken well after culmination.
The phase always looks much smaller in images than the calculated phase,
probably due to the sharpening.
Details in IR are debatable, but the UV markings are clear here, as is their
rotation in a period of 4 days.
