I had a brief window of opportunity to shoot the Sun this morning before the cloud closed in again. Unfortunately I couldn't escape the cloud altogether, so the composite image contains artefacts that are due entirely to the cloud and not the Sun - ignore the brighter irregular polygons around the Sun's periphery! Equally unfortunately I was unable to get the detail I wanted due to the cloud, but there is sufficient there to show that the main sunspot groups are still in situ and still very active, in fact, if anything the new group on the left upper limb look to be still growing.
23 images comprise this composite image, processed in PIPP to crop and centre the subject, then in Registax to create the composite and finally in Photoshop to add the Orange Filter.
The camera was the Sony a-290 and Minolta 75-300mm zoom lens combo. Settings: 1/4000s at f/5.6 and ISO100.
