After spending an amount of money one should not spend for a past time, getting the camera last week and then waiting 7 days for clear skies - finally.
Below is IC1318, the nebula in Cygnus. I chose this target because it was relatively high in the sky (advantage in a light polluted city), but not too close to the zenith (which makes guiding a pain).
The image is the result of 5x5 min of H-alpha, H-Beta, O-III and SII. Because of the short exposure time (I was still playing around), only H-alpha and SII really had significant impact.
I also learned some lessons. Make sure to remove all dust from the sensor glass and really go for long exposures. Narrow band also means a lot less light.
