The comet, as seen by a 'normal' camera lens on Sunday evening. (It's not a telephoto lens and it's not a wide-angle lens.)

First photo was taken in fairly bright twilight. The comet (C/2025 A6 Lemmon) is the only 'alien green' smudge near the middle of the frame.

Second photo was taken 17 minutes later near the end of twilight. (Full night would start about 5 - 10 minutes later.) A bit of tail is now visible, many more stars, and lots of @#$! satellite trails.

Third graphic is a finder chart from planetarium software. The red wire rectangle shows the sky coverage of the photos. I have also extended this finder chart more to the right to show the Big Dipper. This finder chart is for 19 October, but the comet will move only a little bit to the left every day. By the 23rd the comet will have reached the edge of the photo frame...and moved a wee bit higher.

A finder chart showing the comet's location relative to brighter stars. The red wire rectangle shows the sky coverage of the photos.

In dark twilight the comet's tail is visible. A band of sky near the horizon is a dull orange-red. The rest of the sky is dark blue. More stars are visible.

Comet becoming visible as twilight gets darker. The sky along the horizon is still yellow and orange, but the rest of the sky is a dark blue. Some stars are visible.
