This is a faint emission nebula in Cygnus, near Deneb. Initially thought a planetary nebula, it's now classified as an emission nebula. Here's how I captured it: using an Astro-Tech AT115EDT telescope, ZWO ASI2600MM Pro camera, Antlia 3nm filters, iOptron CEM70 mount, ASI290MM Mini guider, ZWO ASIAIR Pro control hub, 40 dark, flat, dark-flat frames for calibration, Astro Pixel Processor for stacking, Photoshop and Starnet++ for editing, with a total exposure of 20 hours.
