I am not sure about the real FWHM of my images, I guess it is quite far from ideal.
I just measured that Sodium double lines are 57 pixels separated, I always use one pixel width to merge the spectral lines.

Wah,
You have certainly come along way with your SHG in the past few months.
Well done!
The Sodium doublet is 6A apart (5890>5896A), with 57 pixels this gives a dispersion of 0.1A and a probable resolution close to 0.2A

You have mastered removing many of the worst artifacts and the images really are starting to look photographic in quality. The Mg image is outrageous, looks like a weak calcium image.

I just uploaded the Na line.
The "2nd" picture now becomes "3rd" picture.

The Na image is quite flat that active regions are not as obvious as others.

Nice images, Wah.

Is that a Ca 4226A image? Surprising contrast in the faculae - even more than the Mg b line.

Guys,
I currently hold stocks of the Surplus Shed Adjustable slit assemblies.
If you need one, they are $25 plus postage.
Let me know.
