Sun - 27.8.2021 at 17.17 Rautalampi Observation number 100741

Visibility III / V

Vesa Vauhkonen, Sisä-Savon Ursa

The sun also showed up. I tuned to the stand of an old super zoom with the Neutral Density Filter (attenuation 1/100000). As many as 10 image stack, 100% stack.

The comma structures stand out reasonably well, even though the image is pretty much crumpled.

Color and mv versions.
