3.5 hours of Earth's rotation

Single frame with old rokinon 14mm f/2.8 lens at f/4 and Canon 6d at iso 100.

I was happy with the result, because in the photo you can see, on the right, the shadows of the Milky Way "descending" and the clouds of Magellan, on the left, "rising".

The tallest shadow is the Small Magellanic Cloud and the lowest is the Large Magellanic Cloud.

I didn't risk putting the camera on a tripod, as a small wind would disturb the tracks (in a long single frame).

I placed it on a large stone with two weights slightly on the sides, so that there would not be any shaking. Wind on the camera tape (for those who still use it) or a slight breeze can spoil many tripod shots.

This old 14mm lens is not satisfactory for normal astrophotography (at least for full frame ), as it gives coma up to the middle of the photo at the largest aperture
( f/2.8 ) In cropped cameras, I believe, this "defect" is smaller .

You have to set it at f/5.6 and cut 20% of the edges or at f/8 to get the entire field sharp (which makes it almost impossible, for normal landscape astrophotography photos, in full frame).

After all, this "defect" is extremely useful and interesting in star trails, as it distorts the trails more than it should and gives an oval format to the sky.

The “AstroBin Image of the Day and Top Picks”, or IOTD/TP, is a long-running system to promote beautiful, interesting, peculiar, or otherwise amazing astrophotographs, with a focus on technical excellence. Learn more.

Submitted The date and time when you submitted this image for IOTD/TP consideration.	...
Views by Submitters (available since September 19th, 2023) Every image is assigned to 50% of available Submitters. In the event that at least 80% of them don't view the image before its time in the IOTD/TP process expires, it's assigned to the other 50% of Submitters and the process begins anew.
Promotions by Submitters When 3 distinct Submitters promote the image, it moves on to the next stage of the process: evaluation for Top Pick status. This requirement, in addition to anonymization of images and distribution to only a subset of them, prevents biases and ensures that the best images are selected.
Promotions by Reviewers When 3 distinct Reviewers promote the image, it moves on to the next stage of the process: evaluation for IOTD status.
Early dismissal Staff members have a lot of images to inspect on a daily basis, and they can dismiss images if they believe they don't meet the requirements for IOTD/TP selection. If an image is dismissed 5 times, it's removed from the process. This streamlines the process and ensures that any bias present in promotions could be overruled by other staff members.
