M42 "Orion Nebula"

M42 "Orion Nebula" through a duoband filter. Total integration 19x2 min. Some frames were discarded, something happened with the tracking while I was drinking tea. Therefore, the result is a bit noisy. It's a pity the SV220 produced halos around bright stars. Apparently, either a little dew formed on it, or it just has that characteristic.
