Comet Lemmon (C/2025 A6) in the morning sky, just before twilight starts.

The camera was on a fixed tripod, no tracking, short telephoto lenses. 30 images were taken, then stacked with software.

This comet is faint to the naked eye, pretty in binoculars, and it's only seen in the northern hemisphere.

Note that in the first photo, if you zoom in close, some of the stars are elliptical smudges. Those are galaxies, tens of millions of light years away.

If you don't want to get up at 5:30 am, wait a day or two and it'll be visible low in the northwest in the evening sky, getting higher and moving south day by day.

If you can get away from bright city lights, this comet is bright enough that even a cell phone (especially propped on a stationary object) can get decent photos.

Please boost and share widely, especially the finder charts.

A finder chart for the evening of 20 October. Use the orange star Arcturus, and the handle of the big dipper to orient yourself to the sky.

A finder chart for the morning of 18 October. Use the Big Dipper and its handle to orient yourself in the sky, then look to the right and a little lower than the lowest star of the handle. This shows the sky just before twilight starts.

The head of the comet is green. The narrow ion tail is faint blue and has some texture/knots in it. the comet also has a wider, shorter dust tail that is slightly yellow. — This image is a crop from the entire frame, taken with a 135mm lens.

The comet has risen above distant conifers. The tail, though faint, stretches across most of the frame.

@KrajciTom Great photos! It's been cloudy here a solid week, I'm hoping I'll get a chance to finally look for the comet tonight
