I'll post today two crops, 100% of the resolution and on a quarter of the image, clarify if not add them to the original frames, two images that seem very interesting due to the high definition of many of the phenomena which occur during the explosion.

Loving the volcano shots mexhunter. Quite mesmerizing.

And Damian Peach's sequence of Io transiting the limb of Jupiter made me drool. (Even though the numbers are a little bit muddled.)

Double Iridium Flare in Leo Constellation

I Used a Canon EOS 700D camera, unguided, on a tripod. The background pic is an integration of 30x10 shots at ISO 800 at 24mm focal length, with 5 dark frames. The two flares are taken separately both in 30 ISO 800 shots. Then processed and combined together via software.
