I got outside tonight/morn, couldnt sleep, got a bunch of shots, added a sock over then lens to insulate for now. Here's the
moon crescent through the low cloud and developing fog this morning, jpg straight from camera. Cant see any chromatic fringing. Should be a good lens for the sun too when i make a filter for it. Not finding any meaningful faults with it yet, for regular photography it'll need good manual skills which i dont have anymore and its a solid simple option that beats any comparable lens and less complicated than a scope with flattener and extensions etc.
