Instructor: Dr. Christian Sasse, Astronomer-in-charge of iTelescope
Summary: In this instructional video, you will learn how to process the very rare Cederblad 211 (aka R-Aqr) binary system using Astro Pixel Processor (Astro Pixel Processor) and Topaz Sharpen AI (Sharpen AI). To help you follow along with this instructional video, Dr. Sasse has made available the stacked images taken, over several nights, with a 24-inch telescope on the iTelescope network.
Christian also shares information on this binary system which consists of a red giant star and a white dwarf in a symbiotic relationship. Additional information on this interesting binary system can be found in the following links:
phys.org/news/2018-12-actual-image-white-dwarf-material.html, skyandtelescope.org/sky-and-telescope-magazine/the-drama-ridden-couple-of-r-aquarii/, aavso.org/vsots_raqr.
In the video, Dr. Sasse shows you how to process the downloaded stacked images taken in both broad-band and narrow-band filters (LRGB, Ha, and OIII), to create a high-resolution final image compared to what the Very Large Telescope (VLT) was able to capture. He has made available 2-hour images each in LRGB filters, plus close to 5-hour images each in OIII and Ha. You can download the stacked images here:

This is a wonderful opportunity to learn image processing while doing, and learning enough about the science behind this interesting binary system to pique your interest for more. We hope you enjoy it!
