Couple days ago had a go with my scope. Just below M30, a bit to right from it found this ..... see image.
Conditions: Typical Sydney light polluted sky ( if lucky can see 4-6 stars). No UHC filter used.
Telescope N250 F4.8 + CANON EOS M ( unmodified i.e. IR filter in) at prime focus. FOV estimated 40 arc.min
Spectral capability: Sensor is CANON specifically developed for astrophotography ( same as on 6D camera). Photo-diodes are sensitive to any frequency from MHz to 300 GHz. Metallized mirror in the scope reflects any frequency, naturally this includes Xray and ?????
Picture is snipped (around 5 arc.min) from full frame. Any astrophysicists there with an idea ..... what the hell is it ?????
