Taken with a Skywatcher ED80 Refractor using a Canon 600D at prime focus. A Baader Astrosolar filter was fitted to the telescope. Best 25 out of 45 images stacked using Registax 6 after centering and cropping each frame automatically with PIPP. This whole process takes less than 10 minutes. Photographic settings :--- Scope 80mm Diameter lens at F7.5 giving a focal length of 600mm. ISO 100 1600th sec exposure. Camera in continuous shoot mode to take a rapid burst of jpg images. Scope on a AZ3 Mount so not guided. The Baader film can for scope is homemade as the filter is cut out from an A4 sized sheet that it's supplied in. It's very easy to make a safe housing for the film. The effective focal length of 600mm becomes 960mm when the Canon crop factor of x1.6 is factored in
