My first try at the famous Horsehead nebula with my new H-alpha filter at 7nm. Due to technical problems i wasn't able to capture as many hours as i wanted but still the picture came out pretty decent.
I'm looking forward to buying a cooled CMOS camera, because the noise on my current DSLR is pretty bad.
