A test image of the northern autumn Milky Way from Cassiopeia at left to northern Cygnus at right. The bright North America Nebula and dark Funnel Clkoud Nebula are at right near Deneb. IC 1396 in Cepehus is at centre. This was taken with the Canon RF 15-35mm lens wide open at f/2.8 and at 35mm focal length and with the Canon EOS Ra camera at ISO 800 for a stack of two 2-minute tracked exposures. Taken as part of testing the camera and lens.
The bright and dark nebulas along the northernmost segment of the Milky Way, from Perseus at upper left to Cygnus at lower right. At centre is Cassiopeia and Cepheus. The bright nebulas include — from upper left to lower right: the IC 1805/1848 complex known as the Heart and Soul Nebulas, the Ced214/NGC7822 complex, IC 1396 in Cepheus, and the North America Nebula NGC 7000 and the Gamma Cygni IC 1318 complex at lower right. The dark Funnel Cloud Nebula stands out above the North America Nebula. However, the entire field is coloured by subtle streams and bands of interstellar dust adding a yellow hue to the Milky Way. The Andromeda Galaxy, M31, is at lower left. This is a stack of 35 x 3-minute exposures with the Canon RF28-70mm lens at 28mm and at f/2.8, on the Canon EOS Ra camera at ISO 800, on the Star Adventurer Mini tracker. Shot with an URTH Night light pollution filter. Taken from home October 7, 2021. Luminosity mask adjustments applied with Lumenzia. A mild Orton glow added with Luminar AI.
Horsehead and Flame Nebula area of Belt of Orion. Taken Jan 17, 09 with 77mm f/4 Borg astrograph lens (300mm focal length) and Canon 20Da camera at ISO 400 for 4 x 15 minute exposures. On AP Mach 1 mount. Autoguided with SBIG ST402 camera and PHD Guider. Excellent night but lots of snow and sky was good but somewhat lit by snow illumination.
