The Veil Nebula in Cygnus, a supernova remnant. Includes NGC 6960 (at right), NGC 6992-5 (at left) and the central NGC 6974 and NGC 6979 components. This is a stack of 5 x 15 minute exposures with the Canon 5D MkII at ISO 800 with the Lunt 80mm f/7 doublet apo refractor and Borg 0.85x field flattener/reducer. Taken as part of testing.
8-minute exposures at f/4.5 with AP Traveler apo refractor. 20Da camera (second night out with it) at ISO800, on warm summer night. In camera LENR On. Taken Aug 1, 2005. Two image stack with top layer at Normal 50% for noise reduction. Noise Ninja filtering also applied. Notice the sky color difference on either side of the main arc -- it is expanding into an area of sky wiht more interstellar dust, so the sky and stars to the right of the arc look yellower, reddened by dust. The sky to the left looks more neutral.
8-minute exposures at f/4.5 with AP Traveler apo refractor. 20Da camera at ISO800, on warm summer night. In camera LENR On. Taken Aug 4, 2005. Stack of two for noise reduction, both layers also Noise Ninja filtered. Colors not enhanced except through contrast boost.
