M33 in just under 16.5 minutes

Nothing to see here...except some photons that travelled for nearly 3 million years to reach the tiny pixels, in my tiny camera, on a little planet, in a single solar system, in a 'timeless' universe. In a little over 15 minutes there was sufficient electrical signal to provide a 2D image of this enormous 3D galaxy, 60,000 LY in diameter and estimated to contain over 40 billion suns. Extraordinary, you have to agree! [Wikipedia]

First recorded in 1654, and catalogued by Charles Messier a hundred years later, and the spiral form described by Lord Rosse using his 72" 'leviathan', its true glory was only revealed with the advent of photography. Without detracting from the extraordinary achievement of these pioneers and the knowledge they imparted, I'm always amazed at the detail I can see with my tiny 1/2" chip, in a 3" scope.

A handful of 120s frames were captured in Envisage, aligned, stacked and processed in Nebulosity. M33 certainly deserves much more attention...but probably not until better weather and Autumn skies return later in the year.

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.
