as you know I have been playing with Lunt etalon and Sol'ex together 1 ) normally a scan without etalon looks like following normalscannoetalon.jpg 2) but a scan with etalon looks like something from a inverse universe etalonscan.jpg v4.3 software fails cause it is looking for a dark line, any way o...

Montana seeded my mind with an Idea about using Sol'Ex with a LUNT etalon it was near sundown. (defined by tree in way not time of day) but I did get one shot of Frequency comb. 3rd one down is H-a line. notice Sol'Ex is more narrow which I think is kind of cool. more testing at next opportunity. Ca...

in that era it was thought that extra lens would be needed to fix any residual SA error it was later proven by Fraunhofer that you only need 2 lenses. however, there was by luck some improvement in CA and a flatter field. this led to Cooke lens and started people thinking about apochromats but this ...

sol ex is more adaptable with different scopes.
