M43/Orion Test-shot with broken Sigma lense

I have an broken old Sigma 70-300mm (f5.6?) lense lying around, so I wanted to see what it could do (knowing already that it would be bad). I've used my Canon 1000D DSLR...

I removed some eletronics from the lens and fixed it at 300mm and infinity.

Quickly setting this ut on a goto altaz mount, not paying too much (roughly none) attention to focus and aligment.

I've selected one 30 second shot (ISO800), I've only streched the histogram.

There is distortion, vignetting, cromatic aberations from the lens, and tracking errors, vibrations, and shearing from the mount... Wow...
