Image Details:

it was 37C on Saturday, the first "hot" day of Spring/Summer here in Perth WA.
Perfect to get outside and image the Sun in H-Alpha :)
Impressive filament toward the bottom of this pic, which I have inverted the B&W before adding false colour back in - which is why the sunspots appear light, rather than dark as expected.
