Yes, it is designed specifically for telescopes in the 8 to 12.5-inch range. With a 13-inch illumination diameter, it provides sufficient coverage for a 12-inch aperture.

The unit is versatile and can be manually placed directly on the front of a vertical optical tube. Alternatively, it features eight #6-32 threaded holes, allowing you to hang it in a park position for easier access during your imaging sessions.

Absolutely. The Flat-Man L is controlled via Windows software, which allows you to precisely adjust the brightness levels to match your specific exposure requirements and ensure consistent calibration.

Electroluminescent technology provides a highly uniform light source across the entire panel surface. This consistency is critical for creating accurate flat frames that effectively remove vignetting and dust shadows from your final images.

The included software is compatible with Windows XP, Vista, 7, and 8. If you are running a newer version of Windows, you may need to check for driver updates or compatibility modes, as the software is legacy-based.
