A wide-field image of the area of sky around blue-white Altair, bright at centre, flanked by Alshain (Beta Aquilae) at bottom and orange Tarazed (Gamma Aquilae) at top. Above Tarazed is the dark nebula known as Barnard’s E, named for Barnard who first photographed and cataloged dark nebulas. The E consists of B143 (the darkest component) and the less prominent B142 below. B334 is at top right, while B340 is left of Tarazed. This is a stack of 6 x 6-minute exposures with the William Optics RedCat 51mm astrographic refractor at f/5 and the Canon EOS Ra at ISO 800 with LENR on as it was the warmest night of the summer, August 18, 2020. Aligned, stacked and median combined in Photoshop to eliminate some satellite trails. Autoguided with the ZWO ASIAir and ASI120MM guide camera with the RedCat on the Astro-Physics Mach1 mount. No filters employed here.
