M27 first use of H-Alfa

I could image this object for a few clear nights. After all summer travelling and garden work, I could finally do some imaging again. This was not only the first use of an H-Alfa filter narrowband, but also new equipment: I switched laptops, so needed to re-install all software and needed to get all hardware working on it. That took me two hours. Also an Starlight Express automated filter wheel, and a Pegasusastro Focuscube were used for the first time.

I have some issues getting all the Ha detail (the internal structure and the outer halo) also visible in the color RGB combination.

Jupiter and Antares

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.
