Sun in H-alpha 3pm BST 02/04/16
Taken from Oxfordshire, UK with a Coronado PST, 2x Barlow & slimline T-ring attached to a Canon 1100D
Shot through quite a lot thin high level cloud.
ISO-800 1/60 second exposure
324 images shot and the best 50% stacked using Autostakkert! 2. Resulting stacked image was processed using Adobe Lightroom, Photoshop CS2, Focus Magic and Faststone Image Viewer
I over exposed the photos so the area which suffers from the "spotlight" effect you usually get with this telescope has completely blown out, leaving most of the disc featureless. Howerver, I was lucky enough that the only active region currently visible was just outside the area that I over exposed and these 2 huge prominences came out ok
