Bode’s Galaxy, M81

Steve Fox, Camberley, Surrey, 22 January 2020

Steve says: “I took this from my light-polluted back garden near Camberley. I’d tried to capture

M81 before with my unmodified

DSLR without much success, so I used my new

mono CMOS camera with narrowband filters

to try to minimise the effect of light pollution. I’m still on a very steep learning curve, but I was extremely pleased with the difference

the filters made to the final image.”
