The region of nebulosity on the Cepheus-Cassiopeia border with NGC 7822 (top) and Ced 214 (bottom). This is a stack of 15 x 7 minute exposures at f/4.4 with the 92mm apo refractor and filter-modified Canon 5D Mark II at ISO 800. Taken from New Mexico. Focus is a little soft.
NGC 7822 (above) and Cederblad 214 (below), a pair of emission nebulas and HII regions on the Cassiopeia/Cepheus border. This is a stack of 8 x 12 minute exposures with the Canon 5D MkII (modified) at ISO 800 and with the A&M Officina Stellare 80mm f/6 apo refractor and Borg 0.85x flattener/reducer which was not quite a match for this scope, as the corners are still aberrated.
A contrasting region of the Milky Way — with the bright emission nebula, the North America (aka NGC 7000), below the dark mass of the Funnel Cloud Nebula at top, aka LeGentil 3, an obvious naked-eye sight under a dark sky. To the right of the North America below bright Deneb is the less obvious dark region known as the Northern Coalsack. This is a stack of 10 x 3.5-minute exposures with the 135mm Canon L lens at f/2.5, on the old (2009-vintage!) Canon 5D Mark II camera at ISO 1600. The 5D II is a filter-modified camera from AstroHutech. The camera was on the Star Adventurer tracker. About 1/3 of the frames were slightly trailed. I used the best 10 for this stack. Light cloud or haze added the natural star glows, However I did have a NiSi Natural Night light pollution filter in place to further enhance the contrast and nebulosity. Faint nebulosity brought out with luminosity masks. A mild Orton Glow artistic effect added with Luminar AI. Taken from home September 7, 2021.
