Hi everyone.

I've had a frustrating intermittent problem with flats for some time now.

This morning was a good example - half way through capturing a series of early morning sky flats, under more or less evenly lit cloudy skies the images appear to have a series of vertical bands or stripes running through them.

Previously, suspecting electrical interference, I'm managed to somehow resolve the problem by separating all cables and cords from one another, switching on /off the camera, removing and replugging in the cables, restarting Nebulosity and sometimes even the laptop.

But here it is again - this time though the effect appears mid sequence.

It's a QSI 8300wsg8 camera, I capture with Nebulosity 3.0 on a mac.

Any ideas?

Cheers

Andy
