Geoptik Flat Field Panel for 292–372 mm Telescopes

Geoptik Flat Field Panel for 292–372 mm Telescopes

Description:
Image calibration is a key step in astrophotography. It removes optical defects, sensor dust, pixel sensitivity variations, and vignetting. This results in better data quality and cleaner final images.

The Geoptik Flat Field Panel produces a uniformly illuminated surface for high-quality flat frames. It fits telescopes with diameters from 292 to 372 mm. The panel is easily attached using three plastic screws for quick and secure mounting.

Brightness is controlled by a built-in rheostat to adapt the light intensity to your telescope and imaging setup. It runs on 12V DC via a supplied cigarette lighter cable, making it ideal for field use.

Technical specifications:
– Compatible diameter: 292–372 mm
– Illumination: uniform electroluminescent panel
– Brightness control: integrated rheostat
– Power supply: 12 V DC
– Cable included: cigarette lighter 12V plug
– Mounting: 3 plastic screws
– Use: flat frame generation for image calibration

Additional info:
This panel is essential for eliminating vignetting, dust shadows, and sensor inhomogeneities. It ensures reliable calibration frames for advanced image processing.

The image above shows a typical flat field with obvious and slightly uneven vignetting. This is normal with most telescopes.
