Sun in different wavelenghts using Sol'ex


Using my Sol'Ex I'm able to image the sun in different wavelenghts, like H-alpha, H-Beta, Magnesium b1, Helium D3, Ca H, H-alpha doppler. Never thougt I was able to do this.. but see, using my Sol'Ex it became reality.

He I D3 image of Sun June 8

I made different video's of the spectrum near Na D1 and Na D2 in view of procession He I D3 line.
I used JSolex version 2.4.4 using automated detection and full process. Next I searched manual the Spectrum line using Spectrum Debugger. Processing the image with Imagemath :
fixing_banding (clahe (img(Hed3) -continuum), 1.5), 30,20)

Set up :
TLAPO 60/360 f/6, Hoya 1.6, Sol'Ex, ASI290MM
Sharpcap 4, JSolex, IMPPG, CS4

I compared my he I D3 with the one from Didier Favre from the same day and is comparable.
