Mars - 24.10.2020 at 01.22 Espoo Observation number 94409

Visibility III / V

Janne Sievinen, Ursa (Helsinki)

It still didn't hit very good and even weather on its own in the Mars descriptions. However, so many moderate random squares were found in the clips of a couple of thousand squares that they could stack the general features of the planet's surface. Of course, this approach works, too, but focusing is quite challenging in weak weather - especially with a rigid and slippery manual system.

The image is a stack of 314 frames imaged through a 742 nm IR transmission filter.
