The Pacman Nebula, NGC 281, in Cassiopeia, near the star Alpha Cass, aka Shedar, at right This is a stack of 10 x 6 minute exposures with the filter-modified Canon 5D MkII at ISO 800 through the TMB 92mm apo refractor at f/4.4 with the Borg. 0.85x field flattener/reducer. Taken from New Mexico, Nov 18, 2014.
The small emission nebula NGC 1491 in Perseus, with the large bright star cluster NGC 1528 at left. The field has other faint nebulosity throughout. This is a stack of 5 x 12 minute exposures with the TMB 92mm apo refractor and Borg 0.85x flattener/reducer for f/4.8 and filter-modified Canon 5D MkII at ISO 800. Taken from home Oct 9/10, 2013.
NGC 1499, the California Nebula, in Perseus. This visually faint emission nebula (but easy to capture with a camera) shines above the hot blue star Zeta Persei, aka Menkib, and is surrounded by other faint threshold nebulosity. This is a stack of 8 x 8-minute exposures through the Borg 77mm f/4 astrograph and with the Canon EOS Ra red-sensitive mirrorless camera, at ISO 800. Stacked, aligned and processed in Adobe Camera Raw and Photoshop 2020. No nebula or light pollution reduction filter was employed in taking the images. I shot this from home November 25, 2019 on a very fine if frosty autumn night. The Dew Destroyer heater coil from David Lane wrapped around the front objective lens nicely kept off the frost.
