News Equipment Observatory Astrophotography Projects About me

The sun is a very active object, although it may not appear like that. Using white light filters, active regions (sunspots) can be seen. These spots change shape in a few hours or days time and can give rise to huge explosions and coronal mass ejection (CME's) sparking auroras on earth or disabling telephonelines or satelites. Observing the sun in hydrogen alpha wavelength (Ha) even shows more activity. With my Coronado Ha telescope I can do that, making it even more interesting to study them.

This image shows the partial solar eclipse of may 31, 2003.
date: may 31, 2003, just after sunrise.
equipment: Kodak DC4800 digital camera.
This is an image of the huge sunspot 652. This was a very active region and it erupted a few days after this image was taken, creating a large coronal mass ejection. This image was published on NASA's site www.spaceweather.com.
date: juli 17, 2004.
equipment: ETX105, white light filter, toucam pro 2.
This is an image of the huge sunspot 652 again. Note how the group evolves by comparing it to the image above.

equipment: ETX105, white light filter, toucam pro 2.

This is a close-up image of sunspot 649.
date: august 14, 2004.
equipment: ETX105, white light filter, toucam pro 2.
This image was taken on januari 15, 2005. After a quiet period, another huge sunspot (nr. 720) appeared. This one was even visible to the naked eye just before sunset or after sunrise (when the sun is not too bright to look at) or through thin clouds.
date: januari 15, 2005.
equipment: ETX105, white light filter, 32 mm eyepiece projection and Kodak DC4800.
This is a closeup of sunspot 720.
date: januari 15, 2005.
equipment: ETX105, white light filter, LPI (single best frame).
This is my first image of the sun taken with my Canon 350D..
date: may 14, 2005.
equipment: ETX105, white light filter, EOS 350D, 40mm eyepiece projection.
This huge sunspot (792) was expected before we saw it on the disk: it generated large CME's which were visible before we saw the spot itself.
date: july 30, 2.10pm.
equipment: ETX105, white light filter, LPI, 60 images stacked with Registax v3.
This is my first image of the sun in Ha. I used my PST, 2x barlow, 32mm eyepiece and handheld EOS350D eyepiece projection.
date: december 18, 2005.
this image is a combination of two images I took with my PST, LPI and EQ-2 combination.
date: April 9, 2006.
