Long distance observations

Long distance observations All about the farthest horizons possible to see worldwide. Mostly ground-to-ground covered, but it's also the space for aerial ones.

A rare sunset in Europe is coming. Don't miss out on an unforgettable occasion to catch how the crescent sun goes down behind some characteristic, distant landscape feature you really like. Plan your shots especially within the reddish swath, where the Sun will set as an arc (sunset arc) north of the totality path or as a devil's horns if you live or stay in Algeria.

A good website to come across—it's an algorithm to visualize and compute the most distant place to be seen from the given location.
The tool includes a map with contrasting coloration, where the brightest color represents the largest distance to be traveled from the given place. It changes as we use the zoom scale and browse across the types of regions. There is always the farthest object indicated by a thin line of sight and azimuth. The view can be rendered in Google Earth by using the FOV enlargement. |
Great tool for working with and investigating how far you can see. Unfortunately, no refraction is included.

Recent months have been very productive in collecting and consolidating the relevant, though quite general, information on the development of long-distance observations. They resulted in the world's first publication on this thrilling area of study, stressing citizen science, where anyone of us can be a valuable contributor. Together with DalekieWidoki.PL - Dalekie Obserwacje, the article has been published, and we deeply hope to delve into more details in the future.
The forthcoming subjects to consider could include, in particular, the use of infrared photography in LDOs, as well as broadening investigations of terrestrial refraction behavior.
This paperwork marks the initial step in the scientific process, which this type of photography aims to facilitate.

Just a casual observation, made in a typical mountainous area. Sometimes, even 100km can be a hard barrier to encounter when topography calls the shots. On the other hand, the Hinters Sondwendjoch peak seems to be far away, but it's just 104km from SonntagsKogel. This is simply the summer and quite a high level of humidity, which is not a rule, but it's quite common.

The picture of Ancona—the Italian city on the Adriatic coast — can offer a staggering panorama, especially when "something" additional emerges from the enormous expanse of water.
Head to Chiaravelle, a small hill rising only 96 meters above sea level, just outside of the city, to experience the picture-perfect optical spectacle when the top ridge of the Velebit mountains is visible from the other part of the Adriatic Sea. Distance of approximately 180km. On the right-hand side—the church at Marina di Montemarciano. This viewpoint can be your first port of call when landing at Ancona Airport.

When you are going to Zermatt in southern Switzerland, it's good to pop into the adjacent valley, where, from Saas-Grund village, you can climb Weissmies 4107m.a.s.l. This peak gives you an open view of the Po Valley with the Apennines beyond at a distance exceeding 200km. The farthest Monte Molinatico is visible at a distance of 234km.
