摘要

I made these observations from my backyard in eastern Los Angeles County, using 15x70 binoculars with a 4.4° field of view. Most of the objects we'll visit on this tour are also visible in smaller instruments, especially if they're mounted on a tripod or braced against something sturdy. Equally important for rewarding binocular observing is good dark adaptation. If I pull the hood of my jacket up around my face to block out any incidental light, I'm able to go deeper and see more, even in suburban skies.
