Testing continues


Testing the imaging quality proved difficult to say the least. With nine points to adjust and some structural flexing focusing and collimation is almost impossible. Overall the system seems a bit soft and low contrast, but at least on H-alpha narrowband filters it gave a fairly good resolution on the focused area. Still, the high intensity regions bleed over darker ones reducing the contrast a bit too much. Additional baffling migh help keep the stray light away, but the glow around bright areas does indicate that high contrast isn't a priority for these lenses.
