In order to get professional images, you need to calibrate your raw images with a flat frame. In fact, your photographic system will produce an uneven response caused by: 

• Sensor inhomogeneous response (pixels that are more or less sensitive to light)
• Optical vignetting (image is darker away from the centre)
• Dust on the sensor window (seen as 'donut' shaped spots on the image)
• Internal reflections

To generate a flat frame, you need a homogeneous illuminated screen. Commercial LED panels are unsuitable for this task as they are excessively bright, often not dimmable and frequently have a colour dominance.

The Geoptik flat field panel is the perfect light source to generate a professional flat field with your camera:

• it has a build in rheostat to adjust the light intensity
• it is powered by 12V (a cigarette lighter plug is included) with a 5.5 x 2.1 DC jack.
• it has a balanced spectral emission to avoid colour dominants
• three nylon screws allow to secure the flat field generator on any telescope inclination
• the rim around the generator reduces the white light disturbance (a must have in star parties where white lights are prohibited).
