Sun - 16.5.2017 at 16.30 Espoo Observation number 63985

Visibility III / V


The "test runs" continue and the sun is very dull. However, something small can be found on the surface as well as in terms of prototypes.

What’s annoying with this warranty-exchanged Quark is that this new protut doesn’t seem to show up properly without their separate exposure. The former was unfortunately a better closet in this respect. I wish I could hope for even a few spots on the surface of the sun now, so that shooting would be more fun.

The weather was good, really great, and in addition to the filming, I had to chat with probably ten passers-by and show on screen what a live image of the sun’s surface looks like. It's fun to try to tell others about things, so you don't always have to be alone :)

As a "bonus", there is still a cell phone from the stock.
