Active Region 1184 @ 706nm TiO

AR1184 127mm f17 706nm, originally uploaded by Mark Townley.

This image was taken with a low altitude sun ~ 10 degrees through so high cloud, and given these conditions i'm really pleased with the results. There's plenty of detail visible in the umbra and penumbra, and the granulation is reasonably prominent too. I'm fairly confident that with a higher altitude sun, good transparency and seeing that the results will be considerably better. Taken with 127mm f17 706nm DMK31.
