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.
Images below are colorised using Capture One Pro 8.
For the sunspot I do prefer the white light image, although for other chromosphere activity and prominences it would have to be H-alpha.
