AstroFlat Pro is a 8bf-compatible plug-in for various image editors, including Adobe Photoshop and Corel PaintShop. It helps you balance the luminance levels of astroimages while preserving their detail.

What's more, AstroFlat Pro allows for real-time separation of image details from sky glow, making it easy to handle hot spots and gradients. With simple controls and instantly visible results, users don't need to make any selections. This software works great on individual images, and it's also possible to prepare multiple images quickly for combination.
Optional output of the flat only provides maximum creative control for professionals. Moreover, it allows users to store and retrieve favorite settings with ease. AstroFlat Pro works with 32 and 64 Bit Image Editors on PCs and handles 8, 16, 32 Bit Color, and Grayscale Images. Pixel Math is 32 Bit Floating Point for Max Quality.
Fully color-managed, it's compatible with calibrated and profiled displays, and the zoomable interactive GPU-accelerated preview is fully scrollable. The familiar Photoshop filter-style usability and rich set of standard keyboard shortcuts make it a joy to use as well.
AstroFlat Pro offers full editor integration and supports Photoshop actions and use as a smart filter. The resizable dialog remembers where users put it, and customizable UI - dark and light choices - ensures full flexibility.
For users seeking high DPI display scaling support, mouse-over help is available. Hover over the controls to see quick help, while F1 help provides rich, complete manual and help resources.
Finally, users can try before they buy - the 15 day fully functional free trial allows them to explore all features of the software. AstroFlat Pro requires Windows 7 or newer, OpenGL 2.1, or newer with frame buffer object support. Overall, this software is an excellent choice for both professional and amateur astrophotographers.
