With the moon well past full combined with very clear and dark skies it was time again to do some night sky astrophotography. On an earlier outing, I had taken a few “exploratory” images of potential targets. It was now time to take some longer exposures.
My first target was Rho Ophiuchi cloud complex, a dark nebula of gas and dust that is close to the star ρ Ophiuchi of the constellation Ophiuchus (and located adjacent to the better known constellation Scorpius).
My tools for the night were a Nikon D700 DSLR (fairly old camera technology by today’s standards), a Nikon 85mm f/1.8 lens (a short telephoto lens that works well for astrophotography), a tripod, and an iOptron SkyTracker equatorial mount for tracking the stars on long exposures.
The result isn’t bad considering I’m still pretty much an amateur at this astrophotography thing. For comparison, check out this amazing version of the Rho Ophiuchi cloud complex at the APOD site.
The next night was almost as clear so I returned again to my viewing location near Mormon Lake. This time, I used an ultra-wide angle lens (16mm). Here you can see the Milky Way rising in the east with Saturn in Scorpio and visible in the center right part of the image. The Rho Ophiuchi cloud complex is also visible to the right of the Milky Way. The glow in the lower right is from the city of Phoenix—locateded over 150 kilometers to the south.
While capturing these images I was treated to the yipping of coyotes, hooting of owls, and could hear a small herd of elk grazing in a nearby meadow.
