Hi


Attached are some images of the sun from the 3rd July.
Usual set up with 100mm ED refractor @ f/9 + SHG + ASI 183MM camera.

I managed to capture data at Ha, CaH and H epsilon wavelengths.

The H epsilon (397.007nm) is interesting as it is so close to CaH (396.847nm); only being separated by about 0.16nm.

That's equivalent to 24 pixels on my setup.

** added a continuum and FeI image

Cheers
