Mounted the 28 3.5 PC on the Z5 and tried a couple of long exposures at the Knysna Heads this morning
using a combination of Lee and Benro filters . 10 stop + soft grad ND9 + polariser. I got a couple of reflections of the aperture in the sky which is disconcerting. I don't know but assume they're reflecting off the filter or maybe because I didn't block the eyepiece. Next time I'll try using screen only mode.
