Is this tilt again?

[MARS1960]

FLO replaced my 73R F/R as it was deemed faulty by ES Reid causing apparent tilt.

Here is an image taken with the replacement. 

Does this look like tilt again?

TIA.

It might be - I got two of a faulty batch of FF / Reducers from SW in the summer so it does happen. However, as the stars seem to be pointing out to the edge of the frame it could be the distance from the FF to the sensor that is slightly out. Difficult to tell in the top right as there are no big stars to look at in detail. Maybe try altering the spacing slightly and see if it improves.

Assuming everything is square and tight in the focuser and camera, it looks like it to me.

If you shake -separately- the ff/camera/telescope, can you hear anything loose?

Thanks Alacant, I can hear nothing.

I emailed FLO and they are going to take this one back for a refund too, i have ordered the ZS73A instead, non reducing but at least it will hopefully give me a tilt free flat field.
