Lauri Roche captured Neowise this morning about 12:15 am. Lauri writes: I didn’t have to go far: the balcony of my townhouse. Struggling with aperture, ISO, focussing and an old camera but at least it’s there.

David Lee writes: I was determined to see if I could see more detail in the comet this morning so I brought the Star Adventurer tracker with me. As with most of my imaging adventures something goes wrong. This morning I tried a different mounting not realizing my orientation of the camera would be limited. Usually not a problem when your subject is isolated with no landscape. So my composition is a bit crooked. With this exposure the stars are peaking through and the second tail is more apparent.

Dorothy and Miles Paul walked down to Hollydene Park an hour earlier this morning than yesterday. The comet was even better positioned than yesterday for viewing from the bench at the end of the path, overlooking Haro Strait.
