The region of the summer sky just off the Milky Way containing the inocuous constellation of Lacerta the Lizard at centre here, as a zig-zag line of stars. The field contains the large open clusters NGC 7209 (at right) and NGC 7243 (just right of upper centre). B168 and the Cocoon Nebula are at upper right in Cygnus. 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 obscure contelllation of Lacerta the Lizard near Cepheus and Cygnus off the northern Milky Way. This is with the 135mm telephoto lens and so the field is similar to low-power binoculars. The open clusters NGC 7243 (left) and NGC 7209 (right) are at top. This is a stack of 5 x 30-second exposures at f/2 with the Canon 135mm lens and Canon 5D MkII at ISO 3200 on the Star Adventurer Tracker, layered with a stack of 2 x 30s exposures taken through the Kenko Softon A filter to add the star glows.
This wide-field image frames the main stars of Canes Venatici, the Hunting Dogs — Cor Caroli at bottom, and Chara at right of centre — and to also include in the frame the red star La Superba, aka Y Canum Venaticorum at top. Also in the field are the galaxies M94 below centre, M63 the Sunflower Galaxy at left, and NGC 4490 the Cocoon Galaxy at right above Chara. They are small on this image scale but the image serves for a finder chart illustration of the location of these galaxies relative to the stars of Canes Venatici, and the location of Y Can Ven. The red star La Superba was given its name by Fr. Angelo Secchi, and is one of the best examples of a red carbon star. It is one of the reddest stars in the sky. The field is 10° x 15°, so wider than binoculars. Cor Caroli is a double star but is not resolved at this scale. This is a stack of 8 x 1-minute exposures with the Canon EF 135mm lens stopped down to f/2.8 (thus the diffraction spikes on the stars) on the Canon Ra at ISO 1600, all on the Star Adventurer 2i tracker.
