On planet Venus at ground level temperature level is about 450°C which seems to high for electronic devices such as a camera. Could electronic devices and a camera on a airship just below the clouds endure the temperature at that height and successfully take photos of the ground for a long period ? As far as I know the lower level of the clouds is about 30 km altitude, where the temperature is about 220°C. Maybe it is variable depending on meteorological conditions ? It is also fine if it could take photos only from time to time.
(To get energy the airship could be tethered to another airship one or two km higher. The difference of wind speed at two different altitudes would be used to drive wind turbines on both airships, to provide electric power.)
