Flats Box Geoptik for up to 372mm tubes
Image calibration is a very important first step in processing an astronomical image.
Light Frames are images (or a video) of a celestial object captured by the CCD.
Each pixel in the images will have a numerical value that includes the influences of:
Light from celestial objects in the field of view.
The various types of noise generated by the CCD.
Defects in the optical system.
CCD inhomogeneities (pixels more or less sensitive to light)
Optical vignetting (the image is darker away from the center)
Dust in the CCD window (seen as "doughnut" shaped dots in the image)
Internal reflections
With calibration, we will try to remove as much Bias and Dark Current as possible from each Light Frame.
In addition, we will try to eliminate the effects of certain types of optical defects.
It has a rheostat to adjust the light intensity.
Cigarette lighter cable included.
With its three plastic screws it can be fixed to telescopes with diameters from 292 to 372 mm
