Reducer to Sensor Spacing too close or too far?

[Midnight_lightning]

I'm struggling with spacing and have read lots of conflicting information about how to interpret results. 

This image has elongated stars in the corner - all pointing to the centre. 

I believe this may mean the sensor is too close or too far from the reducer - can anyone tell which is it before I spend another night trying to get it right?

Pointing along the line to the centre (outwards in corner/edges) = too close.

Pointing 90 degrees (crossing) the line to the centre = too far.

Thanks, that was what I thought but then saw a Youtube video that said the opposite.

Hi

It's tilted and a little too close. I found that with my -awful- ed80, getting the corners correct will cause the central stars to get fatter.

Not to worry though, it's easily corrected in software these days:
