Still crap, but I had to do something, whilst mucking about last night.

Could do with a bit more processing ;)  and an interesting flat you have there !

I setup the last five nights only for it to cloud over and have to pack away again so I didn't bother last night.

How on earth did you manage to get a flat like that?

The uneven illumination is due to the chip being uneven and also the scope not being 100% aligned with the chip, it's 13% off centre.  Remember this is an older Sony chip.
