Taken with a Skywatcher ED80 Refractor and a Canon 500D DSLR. A Baader Astrosolar Filter fitted to telescope. Scope at F7.5 ISO200 1600th sec exposure.Focal length is 600mm ( not allowing for sensor crop value ) Best 25 of 55 images stacked with Autostakkert after processing jpg's in PIPP which centres and crops each image and outputs in this case to tiffs ready for stacking. Using jpg's as camera takes these much quicker than raws, and the resultant image doesn't seem any different from raw files. Much faster to process as a result and more chance of getting sharper images due to seeing conditions as can take many more jpg than raws quickly.
