Description

After long snowy, cold winter and cloudy, rainy spring finally summer is here, us astrophotographers can’t say we still have the weather we have been missing. During the eid holiday me and my astrophotography buddies decided to go for a week where the weather seemed clearer to Assos Çanakkale (North east of Turkey). Unfortunately the weather was not what we expected. For this image I actually collected 22 hours of data but at the end nearly half of it was trash due to bad seeing, waxing moon, humidity etc. I also took darks and biases but I found out that there was something wrong with them therefore I changed my mind about using them, instead dithering at 3 aggreviness handled most of the noise in the final result. I was intending to use all the data as this target is really faint but the bad data ruined the integration.

IC 4592 (also known as the Blue Horsehead Nebula) is a reflection nebula in the Scorpius constellation that is lit by Nu Scorpii (wikipedia).
