Rosette Nebula
About this image:
The Rosette Nebula lies at a distance of about 4,900 light-years from Earth, to the left of the torso of Orion the Hunter. Like other emission nebulae, it is a cloud of gas and dust stimulated to emit its own varied hues by the intense ultraviolet radiation coming from the cluster of hot, young stars at its center. Although this nebula can be a challenging object to observe visually, long-exposure photographs bring out the full extent and beauty of this vast celestial wreath, caught in a blizzard of literally tens of thousands of stars.
Technical details:
Optics: 8" f/3.9 Orion Newtonian Astrograph with aperture ring and coma corrector
Mount: Celestron AVX
Camera: Canon 60D unmodified
Guiding: 60mm guide scope with orion starshoot
Dates: January 27 through 30-2022
Location: Taken at my Backyard observatory in Northwest Mo.
Exposure details: 4.5 hours 4-minutes subs, ISO-1250 no calibrations frams
Processing: Pixlnsight, photoshop
