Parallel Bands when Shooting the Sun

Hi,

I'm using a (newish - 2.5 months old) ZWO ASI120 (mono) with a Lunt DS 60 B1200.

When I've used it to shoot the sun I appear to get parallel bands across the face of the sun running from bottom left to top right. I've attached two examples both of which were stacked in registax 6: Sun_142751 (stacked only; no processing) and Sun_142751w (stacked and applied wavelets coarsely to highlight the bands).

I've been using the minimum settings on the camera for exposure and gain; with the Gamma in the off position.

I'm not seeing this effect when shooting the moon or the planets.

Does anyone have any idea what may be causing this? (and I haven't ruled out operator error yet!!!)

Cheers,

Rob
