ISS and Sun (10th Nov 2012)

Another alarm again, from CalSky service. This time ISS would have passed in front of Sun disk at Espoo / Finland, on 10th November 2012. Estimated time was approximately 12:33. I tried to follow, also this time - plans were not successful. Sky was full cloudy...

Partial solar eclipse

This time the observation I had to visually only. No possibilities to photograph it due to busy daily work, unfortunately. It still was a beatiful sight. Sky was partially cloudy. I observed it in southerh Finland (Espoo to be precise), around 12:40 local time (GMT +3h). Approximately 40% of the sun disk area was blocked by the moon.

Sun without spots

My first decent attempt to photograph the sun... This time it did not have any visible spots, image was taken at 20th October 2007. Used equipment were: Baader solar filter foil, Nikon 300/4,5 tele lens and Samsung SHC-721A surveillance camera. This final image was stacked from separate frames with Registax, approximately 250 frames were used.
After taking the original AVI clips, some problems were really visible. Below is one frame captured from the clip. Below and above the sun, the brighter area is visible. This may be due to blooming affect on the camera. Also narrow darker vertical "stripes" are visible. This particular camera has menu, but I have not found any blooming related adjustments there. Looks like this type of camera is not very suitable for high contrast targets...
