Geoptik Flat Field Panel for 206–260 mm

Geoptik Flat Field Panel for 206–260 mm 

Description:
Image calibration is a vital part of astrophotography. It helps correct optical vignetting, sensor dust, pixel sensitivity variations, and internal reflections. Flat frames are used to identify and eliminate these unwanted artifacts.

The Geoptik Flat Field Panel provides uniform illumination for capturing precise flat frames. It fits telescope tubes with diameters between 206 and 260 mm. Three plastic screws ensure quick and accurate alignment with the telescope.

The panel is powered by a 12V DC source using a supplied cigarette lighter cable. Brightness is adjustable via an integrated rheostat, offering flexibility depending on your camera sensitivity and optical setup.

Technical specifications:
– Compatible aperture range: 206–260 mm
– Illumination type: uniform electroluminescent panel
– Brightness control: integrated rheostat
– Power supply: 12 V DC
– Cable included: 12V cigarette lighter plug
– Mounting system: 3 plastic screws
– Use: flat frame generation for astrophotography

Additional info:
The Flat Field Panel is essential for correcting image imperfections such as vignetting, dust shadows, and pixel sensitivity non-uniformities. It helps ensure high-quality, artifact-free astronomical images.

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