Finally got some clear weather, so took out my Celestron 1000/102mm refractor with Solarscope single stack 70mm filter attached to the front. Although I could get visual focus, I found I couldn’t focus the CCD camera with a 2 inch diagonal, so abandoned that and just fitted the CCD camera directly to the single stack blocking filter with a 2 to 1.25 inch adapter.
I visually focused the scope first with a 30mm eyepiece until the sunspots were sharp then swopped in a 17mm eyepiece and focused (tuned) the hydrogen alpha etalon until I could see a rich field of fibrils. The etalon tuned after about 4 turns of its adjustment screw. After that the CCD went in.
I was able to get about 9 mosaic panels of the Sun. Some of them were a bit dim especially around 12 o clock so the mosaic quality isnt great – really should have kept a tight eye on my histogram readings but overall am reasonably happy.
Missed a jet flying across the Sun by a few seconds which would have been a nice image to have!
The top image shows a large quiescent filament at 10 o clock and there is a small C2.3 flare emerging from AR 2248 (checked this against daily solar events calendar at 1333 hrs UT).
