New images with my SHG
hi everybody
my last solar observation was on july 3. I'm a very lazy boy now
the usual 3 wavelengths
a Dopplergram (without rotational shift)
and a not very good magnetogram.
Regards
Phil

Re: New images with my SHG
Very impressive!
Fantastic images.
Please can you explain how you obtained the magnetograph?

Re: New images with my SHG
Wonderful images, Phil. (Welcome back!)
Can you tell me the magnitude of the field in the magnetogram and the corresponding shift of the Fe line?
What field polarity does black / white represent?
I'm assuming you're doing this, as you describe on your site, with a polarizer as well? I'm gearing up my instrument for these studies also.
Cheers.
Peter.

Re: New images with my SHG
Happy to see your responses
carbon60 and Peter, I have a page who describes the method and give som explainations as polarity and scale.
http://www.astrosurf.com/spectrohelio/m ... phe-en.php
If it does not reply enough to your questions, i'll try to continue here
Peter, the lower intensity of magnetic fields that i can record is about 100 to 50 gauss. This magnetogram is not good because the intensity scale is not the same on the whole disk (problem to get a good focus of polarized beams)
