The short of it:
Internationally known astrophotographer, Warren Keller has taught the art and science of image processing since 2005. The author of Springer’s definitive guide, Inside PixInsight, Warren provides One-on-One tutoring, and produces online workshops and video tutorials on PixInsight, Photoshop, etc.
Yada Yada:
Warren has the ability to reduce the difficult concepts of astro-imaging to the essentials and effectively teach them to others. His books, videos and workshops has given thousands of clients the world over, a quick start to creating their own great images.
In 2016-2018, he wrote the definitive book, Inside PixInsight for Springer Nature- the first edition being Springer's top seller in 2016. His video series and books were also named a Sky & Telescope magazine Hot Product. Warren is a member of PixInsight’s development group, and is an official PixInsight Ambassador.
He is proud to have been published as an author and photographer in Sky & Telescope, Astronomy, Sky at Night, Astronomy Now, CNA (China), and many places on the World Wide Web, including NASA’s APOD. Mr. Keller was Atik Camera’s North American representative, QSI’s customer service rep, and was a consultant to Celestron, co-designing AstroFX software.
Warren has presented at the Advanced, the North East, the Midwest, RAW, and CAPS astro-imaging conferences, and was host and coordinator of SWAP in 2013-14 in Tucson. In 2015, he was asked to the board of directors of the Advanced Imaging Conference, where he was VP of exhibitor relations through 2024.

What people say
"PixInsight's valuable set of processing tools can unlock that amazing image hidden within. With any powerful solution comes complexity, and a frustrating learning curve. Warren Keller has been a long-time master trainer in the technical art of image processing. Warren's PixInsight tutorials are a must-see for anyone opening up the PI toolbox. Warren will take you step-by-step through the treasure trove of amazing tools to help you produce the most dramatic images possible. You will not only climb the PI learning curve, but enjoy it at the same time!"
Ken Crawford, Chairman of the Board - Advanced Imaging Conference, Inc., and APOD imager
"As the Science Imager for NASA's Chandra X-ray Observatory, I find that having a diverse toolset is the best approach... You'll find that Warren's warm, conversational style pairs well with the comprehensive skill set offered by him... he is certain to unlock processing mysteries for new and seasoned astrophotographers alike. Thanks again!"

"Having the opportunity to engage on a ‘one-on-one’ basis with someone like Warren is a real treat. Until a couple of years ago, I just dabbled with PI, primarily using it for just DBE. After I made the decision to go ‘all-in’, I realized I wasn’t using many of PI’s amazing capabilities. And after watching a number of PI tutorials, I chose to ‘up my game’ with a couple of sessions with Warren. I have found these sessions to be very helpful, informative, and engaging."
Walt Lickteig- Kansas
"Having had a lot of questions with Pixinsight I decided to try online tuition. I exchanged a couple of mails with Warren and a few days later I was being trained from across the Atlantic. Just unbelievable. The connection was superb and Warren took me through the complete process from raw data to a completed image. His style was excellent and dedicated to my level of expertise with Pixinsight. I was able to ask questions whenever I had one. As far as I am concerned, this was the best investment I made in my hobby. If you are apprehensive, unsure or simply need confirmation that you are doing things right in Pixinsight, Warren is the man to answer all your questions."
Vincent Salfranc- France
"I have worked with Warren now for close to 3 years. I have read both of his books, am a member of his extremely well documented and clearly presented Masters of PixInsight website, attended one of his live seminars, and sat with him during several one-on-one 2-hour long Skype sessions helping me to hone my processing skills. If you are serious about wishing to advance your PixInsight processing talents, there is clearly no one more knowledgeable, thorough, friendly and patient to help you accomplish your goals. His multiple and ever-expanding venues of informational material makes it pretty obvious to me that he loves what he does and plans on being around for the long run, happily providing his clients with great info and effective tutoring."
