Sun in Barium II D2 and H-Beta (June 20)

 




Again, I was able to make a solar image in Barium II D2 (4554A). The image of the Sun in H-Beta was very sharp as seeing conditions were good. This is probably my best H-beta so far.

Setting: Solex Pro 2nd Gen Slit with ASI678MM and Herschel Wedge.
Tilt : 0,017 and Sx/Sy 1,04
Software : SharpCap, Inti, JSolex and CS4
