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 seen by eyes!!!

Nice images, Wah.
Did you try the continuum subtraction for He D3 ?

Yes, I did try once before, but failed to get obvious dark areas.p_zetner wrote:Nice images, Wah.

I need to have the grating upgraded before the next trial.

For the video I captured:
CaH & CaK
https://www.youtube.com/watch?v=cLXI_Kr_W54
I have a question that why I can see 2 bright lines at CaH but just one at CaK?
I don't think it is artifact from the equipment, am I correct?

Hi Wah
shouldn't we see 2 lines at CaK and one line at Ca II H

Hi Wah
you are right, the Ca II H line is on the red side of the CaK

Hi Wah.
Just noticed your question on this thread.
The 2nd bright line near CaH is, most likely, H epsilon at 3970 A. This will also give bright emission near the limb.
Cheers.
Peter.
