My favourite target for testing telescopes, the North America Nebula, NGC 7000, in Cygnus, with its companion Pelican Nebula to the right, aka IC 5070. The bright star Deneb is at upper right. An odd little red nebula is to the right of the Pelican, of unknown identity as it is not in Deep Sky Atlas, Millenium Star Atlas, TriAtlas or SkySafari. This is a stack of 15 x 6-minute exposures with the Astronomics Astro-Tech 90CFT apo refractor and its Reducer/Flattener for , as part of testing, and with the AstroGear modified Canon R camera at ISO 800. On the AP Mach 1 mount and auto-guided with the Lacerta MGENIII stand-alone guider. No filter was employed here, other than the Optolong IR Cut filter installed in the camera itself by AstroGear, replacing the Canon sensor filter. Stacked, aligned and processed in Photoshop. with Lumenzia luminosity masks applied to a starless layer created with RC-Astro Star XTerminator to bring out the nebulosity independently from the rich starfield. Plus layers with PhotoKemi Nebula action and ON1 Effects Dynamic Contrast filter applied to further enhance the nebulosity and contrast. Taken from home on a very fine warm and dry night, May 12/13, 2023, though with few hours of darkness at my latitude of 51° N in mid-May.
