 What's New

IP4AP boards a new vehicle called PixInsight for which there is tremendous interest!  For this mission Warren has teamed with PixInsight expert Rogelio Bernal Andreo.

PixInsight Part-1 Now complete and available via Streams or DVD. We'll get you comfortable navigating in PixInsight. You'll learn how to Reduce, Align, and Combine quality master files; and while still in the linear space: repair Gradients with ABE and DBE, achieve proper color balance with ColorCalibration, and restore sharpness with Deconvolution.

PixInsight Part-2 Now complete and available via Streams or DVD. We'll perform permanent, nonlinear stretches, reduce noise, develop amazing detail, and perform many other enhancements using the power of multiscale wavelets transformations.

Working with Imagers Worldwide

"A couple of sessions on the sophisticated use of Photoshop and Astroart led me out of the dark basement into the brightly lit ground floor and further up. Astrophotography is a high-rise building and Warren is the perfect guide."
