Re: SHG 1st light of 2016: AR12529 in H alpha

well, first trial failed....

I think that it come from using a zoom lens as a collimation : I could achieve to get a proper focus.
Middle of the sun was ok, edge a disaster...

Are you placing an ERF in front of you catadioptric?

Re: Interesting wavelenght for SHG

Forgot your answer...

Nevertheless what is strange is that if you compare both flashspectrum, the one from 2013 shows a FeXIV picture more or less as luminous as He...

Compare to the 2nd one..

Can't we imagine as "suggested" by Ghost -Fire that some days is would be feasible?
