Stack of two 5-minute exposures with Canon 20Da at ISO400 and with 200mm lens at f/4. Taken April 20. Glow layer added to fuzz stars and spikes on stars are from lens diaphram and are not faked in points.
The large, naked-eye star cluster that makes up most of the constellation of Coma Berenices, aka Mel 111. This is a wide view to simulate the field of binoculars. The galaxies NGC 4565 (left) and NGC 4559 (top left) are visible, as is NGC 4494 between the sliver-like NGC 4565 and the main star cluster. I shot this in deep twilight and retained some of the natural deep blue of the twilight from the earlier shots. The differences in star colours show up. The diffraction spikes are from the lens iris blades from being stopped down to f/4 from the maximum aperture of f/2.8. This is a stack of 7 exposures, each 4 minutes at f/4 with the 200mm Canon lens and Canon 6D MkII at ISO 800, unguided on the AP Mach 1 mount.
The Milky Way through the region of the tail of Scorpius, photographed with it high in the sky from Australia. At bottom are the clusters and nebulas of the False Comet area around NGC 6124. Above and at centre are the red nebulas of NGC 6334, the Cat’s Paw, and NGC 6357 (sometimes called the Lobster Nebula, for a “Paws and Claws” pairing). The clusters Messier 6 and Messier 7 are at top left with M7 lost in the star clouds of the Milky Way. The Galactic Centre lies at top left. This is a stack of 5 x 2-minute exposures at f/2.8 with the Rokinon 85mm lens, and filter-modified Canon 5D MkII at ISO 2500. Taken from Tibuc Gardens Cottage near Coonabarabran, Australia. The image could be turned 90° CCW to better resemble its orientation in the sky in which it was photographed in the southern hemisphere, This orientation matches the view in the northern hemisphere.
