We had a beautifully clear sky Halloween night which made for good conditions for imaging the nearly full moon.

The Sun's ever changing surface is endlessly fascinating. These photo sets were taken about 24 hours apart and the changes are stunning. The increased activity on Oct 17th, after weeks of quiet, was eclipsed by multiple eruptions on the 18th. The prominences are made of plasma which is electrically charged hydrogen and helium that have become unstable and burst from the Sun's photosphere into the outer atmosphere.
We've had nothing but rain all weekend, but with fantastic conditions a week ago I had plenty to work on with lots of solar images and one good night to capture a long-departed star in the form of Messier 57 (Ring Nebula).
Not much solar activity last weekend, but it's still fascinating to observe and gave me chance to try out an interference eliminator to reduce the Newton's rings present in earlier captures.
It was a busy weekend with lots of great solar activity. The two images featuring prominences were taken about 24 hours apart and demonstrate just how quickly the sun is changing.
