Tengo un problema. Estoy tomando fotografías con un refractor apocromático William Optics AP 61/360 ZenithStar ZS61 II OTA con f/5.9 y una cámara Atik 460 EX - Monochrome. Cuando tomo fotografías (en este caso de un bloque que tengo enfrente) las luces salen negras en lugar de blancas. ¿Alguien sabe por qué? Uso NINA.


Photo with Atik camera using NINA, 15 sec. 
I put the link to theimage in fits format​​​​​​​

Here you can see that the lights come out white due to saturation with the guide camera, but in the main camera, they come out black.

Photo of the same site with the guide camera, a Titan, using NINA, 3 sec

And finally, the same photo from the same location with the Atik main camera, but with the Maxim DL Pro 5.0 program, 15 sec.

As you can see, the result is independent of the capture program.
The camera doesn't have any "weird" settings.

Any ideas?

Thanks

Looks like your image is inverted… the dark parts are light and vice-verse when compared to the image from your guide camera…

there has to be something wrong with the settings

Why did you image what looks like a building and a street light, was this a test of some sort.
