Disturbed Plage in The Southern Hemisphere - Ha & CaK - 4th July

Old-plage-ha-120-colour old-plage-cak-120-colour Disturbed plage and not much else seemed to be the theme of the sun on the 4th April as these 2 images show. Taken with the 120mm scope at f28 with the Daystar Quark, home brew CaK filter and the PGR Grasshopped IMX camera. I like to be able to image both wavelengths at the same scale as I feel this gives good comparison. Need to be able to do this in Na wavelengths too...
