Artesky Flatfield Generator

A flatfield generator creates a perfectly uniform light source that helps you identify and correct optical imperfections like vignetting and dust shadows on your sensor. By capturing these 'flat' frames, you can calibrate your final images during post-processing to ensure even brightness across the entire field of view.

This model is specifically designed for telescopes with a 550mm aperture. Before purchasing, ensure your telescope's outer diameter fits within the 640mm dimensions of the unit to ensure a proper, secure fit over the aperture.

No, the device uses flicker-free LED technology. This is critical for astrophotography because it ensures consistent illumination even when you are taking very short exposure flat frames, preventing banding or uneven light distribution in your calibration files.

The unit requires a 12V power source and connects via a standard DC power plug. It is designed for mobile setups, so it can be easily powered by most field battery packs or portable power stations commonly used in astrophotography.

Yes, the generator produces a neutral, white-light surface. This consistency is essential for accurate color calibration, as it ensures that your flat frames do not introduce unwanted color casts into your final stacked images.
