The North America Nebula (left of centre) and the Pelican Nebula (at centre) complex in Cygnus, framed with the bright star Deneb. The Cygnus Arc of IC 5068 is at bottom. Smaller Sharpless catalogue nebulas are at upper right, notably Sh 2-112. The nebulas show up well despite this being a "stock" camera, with no filters employed. The field of view is about 7.5° by 5°, similar to binoculars. This is a stack of 5 x 5-minute exposures with the Sharpstar 61 EDPH III apo refractor and its 0.75x Reducer for f/4.4, and the old Canon 6D DSLR at ISO 800, all on the ZWO AM5 mount autoguided with the ASIAir, as a test of the combination of gear. Taken June 26/27, 2023 with the waxing Moon still up but low and setting, and the sky so near solstice was not astronomically dark. No filter employed and the camera is not modified. Nebulosity enhanced with a PK Actions Nebula Filter action and a Detail Extractor filter from Color EFX in the Nik Collection.
