The North America Nebula, NGC 7000, in Cygnus, taken with the new Canon EOS Ra factory-modified “astronomical” version of the Canon EOS R mirrorless camera. Taken as part of testing. This is a stack of 4 x 6-minute exposures, with LENR on and at ISO 1600, through the Astro-Physics Traveler 105mm f/6 apo refractor with the Hutech field flattener.
NGC 7023, the Iris Nebula, in Cepheus with associated dark nebulosity. 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.
The emission nebula NGC 7380, aka the Wizard Nebula (at left) with its associated star cluster also known as NGC 7380. Delta Cephei, a famous double and variable star, is at right, barely resolved here. Delta Cep is the prototype Cepheid variable star, a prime tool for measuring cosmic distances. 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.
