Dawn not recognizing Lights

[jnarro]

Hello,

I have an Atik 414ex, I shot several hours to M42 using Maxim DL, trying to pre process the images with Nebulosity the result was a blue image, so I made everything with Pixinsight but the output still does not like me.

So I tried to use the Dawn workflow to pre process the lights, but I have a message stating that the images were not taken with an Atik camera so any one had this issue before me, all your valuable help will be much appreciated.

Regards

Jose
