The Sun
Active Region 0756
01 May 2005 - 13.19 UT - C8 with Baader Astrosolar filter - ToUCam Pro - 60 frames - wavelet filter
Made on the first hot day (30 deg) of the year, thus poor seeing
Active Region 0652
22 Jul 2004 - 13.23 UT - C8 with Baader Astrosolar filter - ToUCam Pro - 50 frames - wavelet filter
A sudden burst of activity on the Sun after being quiet for months
Active Region 0486, the source of the giant flare of 28 October 2003
26 Oct 2003 - 13.10 UT - C8 with Baader Astrosolar filter - ToUCam Pro - 50 frames - wavelet filter
The Sun is now well past solar maximum and should go towards a quieter state. However, in the second half of October it suddenly went hyperactive showing no less tha three major sunspot groups and on October 28 it produced an X17 flare, one of the largest ever recorded. Active region 0486 was the origin of this flare. Just a day later it spawned another large X10 flare, that caused one of the biggest geomagnetic storms of this solar cycle. Wonderful auroras were seen during this storm at mid-level latitudes on October 30.
Active Region 0375 - 07 June 2003
07 June 2003 - 14.40 UT - C8 with Baader Astrosolar filter - ToUCam Pro - 50 frames - wavelet filter
First try with new full aperture solar filter for the C8.
Active Region 0380(?) - 07 June 2003
07 June 2003 - 14.40 UT - C8 with Baader Astrosolar filter - ToUCam Pro - 50 frames - wavelet filter
New emerging group at the eastern limb.
Sun - 31 May 2003 (Eclipse Day)
31 May 2003 at 8.55 UT (in Denmark) - C5 - Baader Astrosolar filter - ToUCam Pro - 50 frames - wavelet
This big sunspot region was visible to the naked eye (using eclipse shades) and appears in many eclipse photos from this morning.

C5-DX with Baader Astrosolar filter - Vesta Pro - 38 frames - wavelet
A webcam image made during holiday in Denmark. The big spot is active region 0069
Sun - 22 April 2001 late afternoon
ST80 (42 mm aperture) - IRB filter - Vesta Pro - 48 frames stacked - wavelet filter
First light with the new refractor. The entire Sun won't quite fit on the chip but it is a much wider field than I am used to. The image was clearly better with an IR-Block filter installed. The conditions were poor with a haze and thicker clouds drifting around. The large sunspot group near the bottom is active region 9433 which is the old active region 9393 in its second rotation
Active region 9393 - 02 April 2001 at 12:40UT
C5 at f/10 - Vesta Pro - 26 frames stacked - wavelet filter
The gigantic active region 9393 has now rotated across the solar disc to the western limb while still extremely active. It fired two X-class flares shortly before this record. About 9 hours later the same group unleashed a gigantic X20+ flare, the largest flare ever recorded!
Active region 9393 - 24 March 2001
C5 at f/10 - Vesta Pro - 27 frames - wavelet filter
This already large sunspot group grew to twice the size in the following days to become the largest sunspot in 10 years. It caused severe geomagnetic storms on Earth.
Sun - 24 February 2001
C5-DX at f/10 - Vesta Pro - 10 frames - wavelet filter
First solar image with the webcam
Sun - 22 May 2000 at 17:00UT
C5-DX at f/10 - Hi8 camcorder - afocal eyepiece projection - single frame
My first camcorder image of the sun through the telescope. The seeing was poor and clouds interferred a lot.
