The Small Magellanic Cloud (NGC 292) visible from the southern hemisphere, a companion/satellite galaxy of our Milkyway 203,000LY away.
Exposed at 300mm focal length through an Sigma 150mm f2.8 prime lens with a 2X Teleconverter, QHY268M camera, guided with a 80mm refractor at 500mm FL and tracked on a hypertuned CGEM mount.
This image was an experiment where I exposed the luminance channel again at 300mm focal length but used the LRGB, H-Alpha and OIII color data exposed with the SMC at 150mm focal length.
The 2X converter does distort the image a bit, enough distortion where it's better to crop in the wider image rather than expose with the extra glass.
Total exposure time was 20 hours and 1 minute.
