Good news, I can tilt the baader continuum filter (540nm) towards 530nm. The light cone is now central around the Fe XIV line.
I made also 66 scans using my Sol'eX Pro 2nd Gen slit. JSolex 3.3.1 is used to stack the images. Editing was done using CS4, AstroSurface and DeNoise AI.
Binning 2x2 and 14ms, Gain 0.
Some more details are visible but still wat I would expect. Transparency was not 100% and the Sun was about 18° above the horizon. Something to keep in mind next trial.
Anyhow...cool this E-Corona.
