Hello

I own a Atik CCD 383L bought new in 2012 (KAF 8300 CCD).

At present time I noticed an increased difficuty to process my pictures. Every time I had to collect more and more pictures in order to get a more or less dencent image.

So I decided to compare som pictures from the begining of the CCD's live with recent pictures.

Bias are more or less the same, but what a bad surpise.... when I compared darks.

I attached a image comprising the following:
At top, original dark, calibrated dark an bias at 2013.
At bottom recent dark, recent calibrated dark an recent bias.

Sorry but the image was taken from screen using my cell pone.

Is this normal? is it a deffect of my camera? what do you think?

Regards

Geert
