[drawn] non-sexual nudity, high-contrast

An Embrace in Melancholy
[Jan.2025]

I still intend to make another version of this linework with different colouring, but I like this finish too.

Comet C/2024 G3 very low in bright evening twilight as seen from the mountains of southern New Mexico at 9,000 feet. (Thursday, 16 January)

First photo is the comet as first seen in very bright twilight. 200mm lens, fixed tripod.

Second photo is about seven minutes later, just before it set behind cirrus and trees. 400mm lens.

Third photo is another three minutes later. The comet is gone.

Or is it?

Fourth photo is the third photo, but processed to flatten the sky gradient, converted to grayscale, and a very aggressive contrast boost. Traces of the tail can be seen below the band of cirrus clouds. Perhaps even some faint traces above the band of cirrus?

The comet, surprisingly visible in such bright twilight, is a small streak with its short tail extending up and to the left of the nucleus. The sky is a very bright orange just above the trees, and gradually shades to a rich dark blue along the top of the frame. I am trying to convey in this photo how bright twilight was at this time.

Twilight is darker and the comet is much lower in the sky. This is also a longer telephoto lens compared to the first image, so the comet and distant trees are twice as large. A few slight traces of cirrus are above the comet and to its right. Thicker cirrus are down lower and to the right.

The comet has set, leaving some cirrus in the evening twilight sky. But what if we boost the image contrast? (See the next image....)

This is the third image, but the sky gradient has been flattened, converted to grayscale, and a very aggressive contrast boost has been applied. Below the band of cirrus clouds (now a very dark band because of the contrast boost) traces of the outer tail are obvious. Are there faint traces of the tail above the band of cirrus?
