20080105 Sun

The sun becomes active again, we have AR980 and we even got more behind it. Borg 45ED II used, with SM40/BF10 for H-alpha, close up with 3x barlows. APM Herschel Wedge and Baader CaK for CaK shots, close up again with 3x barlows. Both by DMK 31AF03.

1355 (GMT+8), SM40/BF10, Borg 45ED II prime focus, surface detail:-


1356 (GMT+8), SM40/BF10, Borg 45ED II prime focus, prominences:-


Combined with the above two:-

It's grear to learn that the new solar cycle has begun, let's keep watching! During the last year or the last few months, I begin to feel 40mm aperture is not enough, but when it's active again, we will begin to feel the lack of field of view!
