This is what 3.5 hours of shooting from the 'burbs gets you…

M74 is a spiral galaxy of about 100 billion stars. It's face-on to us in the constellation of Pisces, and about 32 million light years away.

But when you're shooting from the light-polluted suburbs of Canberra, it takes a lot of time to get a good exposure after taking out all the "wrong" light.

Jonathan Powles took this shot using a Canon EOS60Da—a special astrophotography version of their standard 60D that has the normal infra-red filter removed—because we like infra-red light in astrophotography!
This is M74, 3.5 hours' worth over two nights earlier in the month. It's low, and I'm shooting from the suburbs, so all in all I'm quite pleased with what the DSLR can do with this given the low surface brightness.
