The next snap of my "heliar" had less noise tthan the previous attempt, but the camera did not really focus at the front surface. While holding the lens so as to get maximum refelctions one would need three hands to get proper framing.
The enclosed crop shows what looks like smudges on the lens, but really is the sun shining on an appletree in my garden, So while better than the Nikkor, certainly not a black hole._DSC1270.JPG
