Measurement of straylight, Mon, Dec 29th 2009
Test of the effect of a light to illuminate an appartment building N of the observatory. The light is of mushrom type with uplight illuminating part of the refractor dome that is reflected back onto the sensor. The light shines through the leaveless trees during the winter.
Measurments of the effect by shielding the light with a white A1-poster (on/off).
Results: on/off difference
All measurments: 1.3 +/- 0.7 mlx (Median 1mlx);
Sensor in Moon-shadow: 0.6 +/- 0.14 mlx;
Sensor in Moonlight: 1.8 +/- 0.4 mlx;

Kugelleuchte bei Ottakringer Bad, Dez. 2011
Nach Gesprächen (GW) wird die Kugelleuchte in den Innenraum des Bades versetzt (5.1)
Abblendung der Leuchte im N der Kuppel (4.1.2012)
Abblendung der Leuchte in Richtung auf die Sternwarte (Durchführung W.W.) am 4.1.2012. Damit sollte der Hintergrund für die Messungen im N um 1.3 +/- 0.7 mlx reduziert werden (sie oben).
