Solar UFO (Or maybe just a balloon!)

I caught a UFO crossing the sun on Saturday. Taken at 08:38BST, 30th April 2016.  It was moving fairly fast so I had trouble tracking it as it took me by surprise. No satellites were predicted to transit the Sun from my location at that time.  Sadly upon aligning, stacking and processing multiple frames from […]

Sunspot Animation (AR2529) in Ha 10-04-2016

Animation of AR2529 (a sunspot), taken in Hydrogen Alpha. The image is inverted so the sunspot appears white against a dark background, as this allows much more of the image detail to be seen.

This is my first attempt, as a bit challenging to create as there were a lot of high clouds drifting through.  This has created  some long gaps between frames and a few odd artefacts around the prominences and disk where I […]
