The Helix Nebula again, this time with data from the Astro-Physics Riccardi-Honders-System at Deep Sky West. The pixel scale is around 1 arcsec/pixel, just as for the previous version from the Astro-Physics Starfire Refractor, but the field of view is smaller. At the same time the system is much faster, total integration time was just over 8 hours as compares to 17 hours with the Starfire.
