Astronomer Eddie Irizarry wrote in an article for EarthSky.org: “Many observers have reported that – once you spot it with binoculars – you can remove them and glimpse this comet as a fuzzy object, using only the unaided eye.
“Using binoculars or other optical aid is a must, though, if you want to see Comet NEOWISE’s splendid split tail.
“If you don’t have binocs, but do have a good camera, a great alternative is to capture a few-seconds-long exposure image of the approximate area of the sky.
“Try at different magnification or zoom settings, and the results should reveal the comet’s nice tail.”
