Geoptik Flat Field Panel for 110 to 164 mm Telescopes

Geoptik Flat Field Panel for 110 to 164 mm Telescopes

Description:
Image calibration is a vital part of astrophotographic processing. It removes optical defects, sensor dust, pixel sensitivity variations, vignetting, and internal reflections, greatly improving image quality.

The Geoptik Flat Field Panel provides a perfectly uniform light surface, ideal for capturing flat frames with telescopes of 110 to 164 mm outer diameter.

Its integrated rheostat allows you to adjust brightness to match your telescope and camera setup. The panel is powered via the included 12V cigarette lighter plug, making it ideal for field use.

Attachment is simple and safe with three plastic screws that gently secure the panel to the telescope front end, without scratching or damaging the optics.

Technical specifications:
– Compatible diameter: 110–164 mm
– Illumination: uniform electroluminescent surface
– Brightness control: integrated rheostat
– Power: 12 V DC
– Included cable: 12V cigarette lighter plug
– Mounting: 3 plastic thumbscrews
– Use: flat frame generation for astrophotography calibration

Additional info:
Flat calibration is essential to remove dust shadows, vignetting, and pixel response variations. This panel ensures precise and consistent results.

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