Glad to be aboard! My name is Warren Keller, currently from WV in the USA. Some of you may know me as an imager and a teacher of astro-imaging via the links below. That being said, I am always learning! I have been a user of Astroart since v. 3, at one time using it for acquisition, and now mainly preprocessing. I've had the privilege of being a beta tester on v. 4 and 5 and being a collaborator of sorts with Fabio on several features of AA5, including DDP and have become a close int'l friend of Mr. Cavicchio whom I greatly admire. I love AA's simplicity and effectiveness and its UI speaks to me in an intuitive way. I detailed the main features of version 5 for artful imaging in our newer Soup to Nuts series available here- http://ip4ap.com/soup2nuts.htm. Avail yourself to the free samples there and enjoy. My personal images are available at www.billionsandbillions.com. Talk to you soon!
