Milky Way

While I was in vacation in Northern Italy this october (2023), I felt the need to take a photo of the beautiful sky with its clear milky way. But I had no astro equipment with me. So I decided to use just my usual camera and a lens to take an image of the sky. The first try was the orion, but it was quite low over the horizon and had bad light pollution. So I decided to point the camera straight up to the zeneth, where the milky way shows up in all its glory. To somehow overcome the problem, that I have no guided mount with me, I used a 24mm lens at f/2 and take as much sky as I could into the image frame. As a first try, I used 15seconds exposure time but the resolution of my 5D IV was so good, that I had no chance to get point-like stars. So I reduced the resolution to 17MP (instead of 30) and set the exposure time to 6 seconds.

I took about 1000 frames this night. To be able to cut a wider field in the image, I decided to use only 500 frames. PixInsight took 3 whoöle days to process the final result and I did not expect to get something useful. At the image borders, there is heavy coma visible due to the fast optics and its problems. The flats I took could correct some issues, but the image stayed quite problematic. So I cut the most problematic regions and included only the heart of what I think is a reasonable image.

It's not ment to zoom in, but as an overview over the milky way, the image works as I wished. At least, it's something... I quite like the result.

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.
