SNR G206-9, a supernova remnant

This is a rather faint supernova remnant in the constellation of Monoceros. This image is an integration of 19 hours of dual narrowband data taken with a William Optics FLT110 telescope, a QHY268C camera and an Optolong L-Ultimate filter. I also took another 10 hours of luminance data.

All post-processing was carried out in PixInsight.
