Fe X, Fe XIV and continuum composition

The full resolution image you may download here.

This color image is a composition of Fe X image (red), Fe XIV image (green) and continuum (white light image).
 
This image is a composition of 554 eclipse images (calibrated using several thousands of dark-frames and flat-fields) acquired with 5 different instruments - Nikon Z5 II camera for white-light (continuum) images and two pairs of ZWO ASI1600MM Pro cameras for imaging of Fe X and Fe XIV emission. Continuum is displayed as neutral gray, Fe X and Fe XIV gave the final image colors.
 
Charged particles are tracers of magnetic field lines. At present, they are the only tools available to visualize the 'shape' of magnetic field lines in the solar corona, thus yielding an image of their distribution in the plane of the sky. However, there are limitations when using ions, such as Fe X and Fe XIV, since they populate different magnetic structures with different temperatures. Hence, the image of solar magnetic field structures, which they provide, is incomplete. Fortunately, free coronal electrons, scattering the photospheric light towards the observer, are omnipresent and therefore the visualization of the solar magnetic field in the white-light (continuum) image is detailed and complete. That is why the composition presented in this page provides valuable information about the structure of the solar magnetic field and at the same time visualizes the distribution of Fe ions.
