Argon sun full disk 488nm

Argon sun full disk lrg, originally uploaded by Mark Townley.

At this wavelength and with this setup the sun is fairly indistinguishable from a continuum image. The PL130M camera works well with this filter and the wedge due to its high sensitivity compared to the DMK31. The 'sharpness' slider on the camera was set too high and as a result there is some vertical banding visible.
