Introducing Monthly Subscriptions 

IP4AP.com is changing in a big way, with the introduction of our low-cost monthly subscription model! This is an 'all you can eat buffet' featuring all of our existing content, and more importantly- NEW CONTENT added frequently!

To date, we've produced separate series, each taking a full-year to complete. While the vast majority of these series remain current and relevant, our new model allows us to add fresh content in real-time, keeping you up to date with the latest techniques and revisions of the covered software.

With this new and exciting change, IP4AP.com also becomes Pix-Centric. While you'll eventually see updated content on Adobe Photoshop and other image processing software, PixInsight becomes our Prime Focus.

What can you look forward to? Object-Oriented video and text-based PixInsight tutorials, User requests for specific tutorials (we might even feature your data!), Access to exclusive content featuring image data, projects, workflow crib sheets, New Instance process icon sets, tips and tricks, Blog entries, and Live monthly internet workshops- some featuring a guest presenter.
