Sunspot AR2529 revisited – Baader Herschel Wedge

With the appearance of that large sunspot end of last week AR2529, I have been looking for another opportunity to image it again – this time in white light using my Baader Herschel wedge. It finally came yesterday. Hence out came my scope for that short period of time.Now it has been a while since we’ve had such a large sunspot; I’ve seen a photo of a sunset landscape where AR2529 was actually visible. As a reminder, the first image was from last weekend in H-alpha.

The images below were captured in white light using Baader Herschel Prism with Solar continuum filter. To get a closer image of the sunspot, I used the Televue 2.5x powermate. AVIs were captured with Sharpcap, processed with AutoStakkert and then wavelets applied with Registax 6.

For the sunspot I do prefer the white light image, although for other chromosphere activity and prominences it would have to be H-alpha.
