This is a "Test" image
and is from the "classic Gold banded" ED glass f/2.8 Manual Focus "mini-refractor" lens. The reason it's labeled a "test", is that it was used for the first time utilizing "step down" rings. I've never liked the star difractions that arise when stepping down the iris. This test (2) rings were used. 72mm down to 52mm, w/ the lens wide open. Used the APS-C T1i. These (all @ 800iso, 22@240s,11@300s & 7@360s) w/ the CLS clip in, were grabbed on different sessions, and included a meridian "flip" (the flip was actually from a different session), so cropped this version, as uncropped shows the frame stacking lines when registered & stacked in DSS.
Did an "L" layer, so it's an LLRB. Not a great result, yet shows potential...also have two more step downs that could be used to reduce 52 to 46 and 46 to 43.
