Flat frames

Yesterday for the first time I took some flat frame with my main camera (ASI294MC), using AIS Air. The pictures were black, even though I used differents time exposition. Where am I wrong? : : :

Hi guys!!

I figured out why it didn't work :

Ok, I used a wrong setup of the exposure-time. I thought to use 1 second, getting black images. Thinking it was not enough I grow up the value: 5 seconds, getting always black images.

Basically the sensor "burned" the images, so using the lowest exposition value I can get better images, even though the histogram was too shifted on the left side. The better exposition value was 0.0045 seconds, figured out only di Autorun session, and after seeing the small pencil beside the exposition time field.

Of course, having better documentation of the ASI Air, I'd have lost less time to understand how to get this result, so, please update the user manual because there are many novice people, like me that don't know how to do.

Thanks

Giuseppe
