Sun - 9.6.2020 at 20.00 Kauhava Observation number 91163

Visibility IV / V

Jari Kankaanpää, Lakeuden Ursa

AR2765 I first tried to photograph a comma cluster with mylar film and visible light. The marvelous difficulty of focusing in my time I assumed was due to thick pollen and intense vibration.

I switched channels to H-alpha frequencies, and immediately got better views.
