Amazing what a difference if you move south with 20° latitude!! That is what happened travelling to Cairo. Constellations and planets are soo much higher in the sky. Was it not for the severe light pollution (estimation SQM 19), the whole constellation of Scorpius would be visible. The upward light rays to the northeast are part of the ‘famous’ sound-and lightshow of the Pyramids.
Yesterday evening, a large break in the eternal cloud pack allowed at last some more imaging! Perfect for the first light of the ASI183MM and also the new guiding/planetary camera the ASI290MM.
During the imaging session, I could picture the setup before and after the streetlights were switched off…. Imagine the difference!Continue reading “Clear again after 2 months!”
Sleeping during a workweek is important! so this image was made unattended – counting on good luck. At the start of the session around midnight the sky was still covered with some high cirrus. At least the street lighting was already switched off.
Image data: Nikon 180mm tele F5.6, no filters, 82x180seconds or about 4 hours of data. It proves the interstellar nebulae are also visible from light-polluted area’s without the use of filters.
