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.
The North America Nebula (NGC 7000) and associated nebulosity and star clusters, near the bright blue-white star Deneb in Cygnus. This is with the Series 6000 Meade 70mm f/5 astrographic refractor (for a 350mm focal length), taken on May 15, 2018. This is a stack of 8 x 5-minute exposures with the filter-modified Canon 5D MkII at ISO 1600, with a ninth exposure blended in to add the glow around Deneb from the high haze passing through during that exposure, to add the colour contrast between the blue star and red nebula.
