Thanks Dave. I viewed the PST CaK sun this morning [image posted elsewhere on Solar Forum] and most plage features clear of limb visible with care via my fluorescent eyepiece 'filter'. Just cupping the hands around the eyepiece revealed an image but a black head cloth best.
I was perhaps too hasty yesterday afternoon under slight haze which is a killer for any detail. The 1/8" 'filter' is stiil too thick and ~1mm thich would be about right;-)
