Summarium
English:
Description: Ocular projection of the sun with large sunspots using a spotting scope (50mm diameter, 45x magnification) and a sheet of paper approx. 30 cm from the ocular. The apparent granulation is due to that of the paper rather than the photospheric granulation. The middle-edge-variation is clearly visible, but may be somewhat overemphasized by slightly in.homogeneous illumination of the projection.
Site and date: Bonn, July 22, 2004, approx. 18 CEST (16 GMT)
Instruments and Software: 15-45x 50mm spotting scope, digital camera, The GIMP
Beschreibung: Okularprojektion mit Zoom-Spektiv Papier (45x, Entfernung ca.
30 cm) in Bonn, am 22. Juli 2004, ca. 18 Uhr MESZ, abfotografiert und nachbearbeitet (aufgerichtet, Kontrast). Die erkennbare "Körnung" stammt eher vom Papier als von der Granulation der Photosphäre. Die erkennbare Randverdunklung wird durch die nicht ganz homogene Ausleuchtung überlagert und evtl. geringfügig überbetont. Weiteres Beispiel für einfache Sonnenbeobachtung.
Instrumente: Bresser Zoom-Spektiv 15-45x50mm (45x eingestellt), Buchinnendeckel als Projektionsfläche, Digitalkamera JD 4.1XZ3, The GIMP zur Nachbearbeitung
