We only have one?

Here is a region with many interesting formations!

In the attached photo you can see the hills north of Appeninus well as the southern Caucasus Mountains, Mon Hadley, and even Promontorium Fresnel Fresnel Rimae are easily visible.

But what really interests us in this photo?

What matters for us Brazilians is a small crater to the left of that accounts for the Fresnel Promontorium suggestive name "Santos Dumont"!

This crater with just 9 km in diameter is only the moon was named a fellow.

Until recently, no more than 10 or 15 years, these make a photo of Santos Dumont in Brazil was unthinkable for a simple amateur astrophotographer. This required large openings instruments only accessible to professional observatories, so that the first Brazilian to achieve photograph it clearly still in time for the film emulsion was our colleague Nelson Travnik using the great German bezel, single CASteinheil in the country, belonging to the Centre Astronomical Piracicaba, this just in on September 20, 1996.

Since then, fortunately much has changed!

The telescopes have become more accessible, affordable and improved optics. Came the technique of CCD and CMOS photo and then the jump was fantastic.

Currently any amateur with reasonable resources can get a pic as exposed below!

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.
