Hello Everyone.
Here is a compilation of solar disk images in four wavelengths from my 13Aug SHG observing session.
(I have four more wavelengths yet to process and analyze!)
Spectral series through the H alpha and CaK absorption lines are also presented.
Note: The orientation of the disks in the spectral series is 180deg from the proper orientation.
Also, the designation of the line-centre image in each series was somewhat crudely done (by eye), so, subject to some error. This means that the numbers showing absolute wavelength offsets are not precise. They are precise in a relative sense.
Cheers.
Peter.

Peter,
Well done mate!
Great spectroheliograms, very well presented.

Mark et al,
One of the significant issues with etalons/ Lyot filters is being able to exactly determine the central wavelength being used -on band? off band? in the xxxA wings??
Not a real problem for digital SHG users.

I'm taking your book away with me on holiday next week Ken for a 're-read', i'm getting close to this SHG malarky

Cracking images, Peter and an excellent example of this methodology.

The series through the wings is very interesting indeed, fabulous work
