Say goodbye to inconsistent flat frames and hello to flawless, professional-quality astro-images!

What are Flat Frames?

In astrophotography, flat frames are essential calibration files used to correct for imperfections in your optical train. These include:

• Vignetting: The natural darkening of the corners of your image.
• Dust Motes: Pesky dust particles on your camera sensor, lens, or filters that appear as dark spots or "dust donuts" on your final image.
• Gradients: Uneven illumination across the sensor.

By capturing a perfectly even field of light with this lightbox, you can easily subtract these imperfections during post-processing, resulting in a significantly cleaner and more professional final image. Note: These are different from "light frames," which are the actual images you take of your celestial target.

Key Features:

• Custom Fit: Precisely modeled to securely attach to the lens hood of a Sigma 100-400mm lens, ensuring no stray light leaks and providing a stable platform.
• Optimized for 5.7" LED: The housing is designed to hold a common 5.7-inch USB-powered LED light, providing a diffuse and even illumination source.
• Freehand Convenience: The snug fit allows you to hold the lightbox over your lens by hand, making the process of taking flat frames quick and easy, whether in the field or at home. No more clumsy t-shirts or tablets!
• Portable Design: Compact and lightweight, this lightbox is the perfect addition to your mobile astrophotography kit.

This tool is a must-have for any astrophotographer using the Sigma 100-400mm lens who wants to simplify their calibration process and achieve stunning, artifact-free images.
