20140601 Wah!'s SHG: H-a, H-b, H-g, H-d, Ca-H, He-D3
Besides the attached images, I have also uploaded some spectrum videos to show these lines in spectrum.
The slit was on the edge of the sun, it is very interesting to see the prominence on the spectrum.
Except CaH and CaK, all other lines/prominence can be see by eyes!!!

- This is not captured with the SHG, but with my PST. SHG is nearly impossible to achieve the same amount of fine details.

- Detail contrast is the lowest among the 4 hydrogen lines. A little bit prominence still can be seen on the left.
