Cygnus area, with Canon 20Da and 24mm lens at f/2.8 for 6 minutes at ISO 400. Tracked on AP 600 mount but not guided. Taken from home on a superb night, Sept. 30, 2008.
Nebulas in Cygnus with the dark Funnel Cloud Nebula (aka Le Gentil 3) at left north of bright Deneb. The field also contains the North America Nebula (NGC 7000) and the complex of nebulas around Gamma Cygni at right, collectively known as IC 1318. To the right of the North America Nebula is the dark Northern Coal Sack. Some light cloud added the natural star glows. The 85mm RF lens is deadly sharp, and very clean to the corners even at f/1.4, with only minimal aberrations at the very corners. Made for portraits, this is a superb lens for deep-sky shooting. This is a stack of 5 x 60-second exposures with the premium Canon RF 85mm f/1.4 lens wide open at f/1.4 on the stock EOS R camera at ISO 400. Being a “normal” camera the EOS R records the red nebulas rather weakly, requiring boosting the reds in post to bring them out at all. The camera was on the Star Adventurer tracker.
Nebulosity in the heart of Cygnus the Swan, including the North America Nebula and Pelican Nebula at left (NGC 7000 and IC 5070) and Gamma Cygni complex at right (IC 1318). The Crescent Nebula (NGC 6888) is at lower right. This is a stack of 5 x 4 minute exposures at f/2 with the 135mm lens and modified Canon 5D MkII at ISO 800, plus another three similar exposure images but taken thru the Kenko Softon filter for the star glows. Taken from home Sept 10, 2013.
