Ultra-Compact Flatfield Panel — Samyang 135mm F2 & Optics ≤ Ø 95mm

Dimmed light output engineered specifically for fast f/2 glass & sensitive astro-cameras

Astrophotography pre-processing requires perfectly exposed Master Flat calibration frames to correct optical vignetting and sensor dust shadows. However, shooting Flats on fast optical systems like the famous Samyang / Rokinon 135mm F2 is often frustrating: standard commercial light panels are way too bright, instantly clipping modern sensitive CMOS sensors even at minimum exposure speeds. The Azur3dprint compact travel Flatfield panel fixes this issue with a custom dimmed LED array housed inside an ultra-compact chassis tailored for optics up to 95 mm (3.74 inches) outer diameter.

🔬 Field Engineering Built for Mobile Astrophotography

💡 Dimmed Flux for Fast f/2 Optics

The LED light matrix intensity has been intentionally attenuated in our workshop. You can finally expose Flats comfortably (0.5s to 2s exposures) at f/2 or f/2.8 without blowing out histogram peaks or dealing with rolling shutter banding issues.

🧳 Ultra-Compact Form Factor (12 cm)

Measuring just 12 cm (4.72") in outer diameter and 47 mm (1.85") in height, this light box is the ideal mobile companion. It slips effortlessly into camera backpacks or airline carry-on cases.

Versatile and Field-Ready Hardware Integration

Engineered to streamline your imaging calibration routine without hassle:

  • Samyang 135mm F2 & Optics ≤ 95 mm OD Fit: Slips flush over the stock Samyang 135mm F2 lens hood as well as any compact refractor dew shield or camera lens up to 95 mm outer diameter.
  • Neutral & Uniform Light Field: High-diffusion panel ensures zero central hot-spots and zero weird color casts across L-RGB and narrowband filter sets.
  • Modern USB-C Port: Features a solid built-in USB-C socket. A USB-C to USB-A cable is included in the package for direct connection to powerbanks, ASIAIR units, or USB hubs.
  • Rugged Black PETG Enclosure: Printed in high-grade technical PETG polymer to withstand transport shocks and heavy night dew.

"If you have ever tried capturing Flats on a Samyang 135mm at f/2 using a standard commercial light box, you know the struggle: even at 1/1000th of a second, your CMOS sensor is totally saturated! By dimming the LED array output, we achieve controlled exposure times around 1 second, allowing camera sensors to operate in their optimal linear response zone."
