FLAT FIELD GENERATORS

 

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.

We stock Geoptik controllable flat field generators in a range of sizes to suit just about any telescope, as well as DayStar solar imaging Flat Caps.
