At our ZWO lab, we testing very new astro images processing software Astro Pixel Processor (APP). APP has many very interesting features and some of them are very unique. Many our customers bought color DSO cameras and a very first  step for all those users during images processing is choosing the right debayer algorithm. APP has a special and unique demosaic algorithm called Adaptive Airy Disc which reduces green and magenta cast in your RGB data, will improve sharpness and will make your stars rounder when compared with other algorithms, for example with well known VNG algorithm. At this test, we compared two debayer algorithms. Left, VNG – Threshold-Based Variable Number of Gradients (Pixinsight software was used) and right, AAD – Adaptive Airy Disc (Astro Pixel Processor software was used). A very clear winner is reference image debayered with APP. Click on image for full resolution!

We absolutely recommend this software for all ZWO camera users. More tutorials and recommendations for ASI camera users coming soon! Try free Astro Pixel Processor (APP)!

  1. Hello Zwo’s,
    Thanks for your dedicated white paper test performance.

    This software looks hugh interesting and my Zwo. Great news.

    Best regards,
