The region of the summer Milky Way in northern Cygnus containing a rich collection of bright nebulas: the North America Nebula at centre and the Gamma Cygni complex at right, plus the dark nebulas Le Gentil 3, the Funnel Cloud Nebula at upper left, the Northern Coal Sack at centre, and the finger-like B168 at lower left. The bright star at centre is Deneb. M39 is at lower left. This is a stack of 6 x 3-minute exposures with the 85mm Rokinon lens at f/2.8 and Canon 6D MkII at ISO 800, on the Sky-Watcher Star Adverturer tracker. An additional exposure taken through a Kenko Softon A filter adds the star glows. Taken on a very clear night from home August 1, 2019. The camera was not filter-modified so the red nebulas don’t stand out as much as they should.
This is a pair of colourful nebulas in Cassiopeia. The Pacman Nebula, NGC 281, is at bottom near the stars Alpha Cassiopeiae, aka Schedar (or Schedir) at right, and eta Cas, aka Achird (above NGC 281). At top are the largely blue or magenta reflection nebulas IC 59 and IC 63 adjacent to the blue star Gamma Cassiopeiae, aka Navi. The tiny blue dot of the planetary nebula Abell 2 is just right of Achird. North is at top in the porttrait format image. This is a stack of 8 x 8-minute exposures through the Borg 77mm f/4 astrograph and with the Canon EOS Ra red-sensitive mirrorless camera, at ISO 800. Stacked, aligned and processed in Adobe Camera Raw and Photoshop 2020. No nebula or light pollution reduction filter was employed in taking the images. I shot this from home November 25, 2019 on a very fine if frosty autumn night. The Dew Destroyer heater coil from David Lane wrapped around the front objective nicely kept off the frost.
Double Cluster and IC nebulas in Perseus. Includes IC 1805 and IC 1848, NGC 896 nebula; NGC 957 cluster left of Double Cluster. Taken Sept. 14, 2007 for stack of 4 x 4 minute exposures with 135mm L-series lens at f/2.8 and Canon 20Da camera at ISO 800.
