The well-known North America Nebula (NGC 7000), with the smaller Pelican Nebula (IC 5067) to the right, in Cygnus, taken in the deep red light of hydrogen and rendered here in monochrome. This shows the rich detail and structure in the nebulas. This is a stack of 16 x 16-minute exposures with the Canon EOS Ra, on the SharpStar 94mm EDPH refractor with its f/4.5 flattener/reducer lens. The camera had a 12nm Astronomik clip-in H-a filter installed. The images were shot over two nights and with the Moon up for most exposures. Autoguided with the Lacerta MGEN3 stand-alone guider. In processsing I used Lumenzia 10 to create luminosity masks on Curves layers to bring out the nebulosity. An application of the Star XTerminator plug-in for Photoshop created a starless layer that was blended back in selectively to eliminate or suppress stars to help accentuate the nebulosity and structure, but without a fully starless image which often shows pockmarked artifacts where the stars were. A high pass filter further snapped up the dark lanes and streaks. A colour grade adds the slight blue tint for artistic effect. All stacking, alignment and blending with Photoshop 2022.
NGC 7000 and nearby Pelican Nebula IC 5067 with TMB 92mm apo refractor and Borg 0.85x field flattener for f/4.6, with Canon 5D MkII (Hutech modified) at ISO 400 for stack of 4 exposures x 8 minutes each. Guided with Solitaire autoguider as a test. Sky not dark yet (moonlight) in first couple of exposures.
NGC 7000 and Pelican Nebula with TMB 92mm apo and Canon 5D Mk II on a superb night, with stack of 2 x 15 minutes + 2 x 12 minutes at ISO400 and Borg 0.85x flattener/reducer for f/4.6. Standard exposure is 12 minutes but the night was so good I did two at 15 minutes with no problem.
