NGC 7822 emission nebula (top, with North up) on Cassiopeia-Cepheus border, with nebula Cederblad 214 at bottom and open clusters at right NGC 7762 (bottom) and King 11 (top). Stack of 9 x 15 minute exposures at ISO 800 with Canon 5D MkII and 105mm A&M apo refractor at f/5.1 with Borg .85 reducer/flattener. Median combined to eliminate satellite trails in 2 images.
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.
