Hydrogen Epsilon and Helium D3 line

I'm very proud about finding the Hydrogen Epsilon line (397,0 nm) near CaII H line and HeI D3 line (587.572nm) near Sodium D1 and D2. The lines were found using JSolex and boosting contrast which made the prominences of the lines visible.

Spectrum are captured using TLAPO60/360 with ASI290MM and Sol'Ex.
