Stellarium and ShowMySky visual model
Stellarium is the astrosoftware developed for many years. There were quite a lot of versions of 0. x meaning, that the work is still in progress. Since 2021, when Stellarium reached the version of...

Solar eclipse below the horizon – the observation guideline
The 2024 total solar eclipse is coming. Anyone interested will be in North America. We cannot forget about the people, who live or will temporarily stay in Western Europe on the day when the...
12P/Pons Brooks comet during 2024 total solar eclipse
This text shows some guidelines for the brief moment of the total solar eclipse 2024 occurrence at twilight, which presumably will allow for a fantastic view of the 12P/Pons-Brooks comet being close to its...
Long distance observations – definition & types
This article is about the general definition of the realm, which has been described occasionally on this website since 2017. Therefore I guess I should have done it much earlier, however better late than...
Is the selenelion lunar eclipse really rare event?
In this text, I would like somewhat to continue the thread from the previous one, which has described briefly my observation of the “just” partial lunar eclipse on Monday morning of May 16th. As...
Just partial lunar eclipse of May 16th 2022
I had a good occasion to watch just a partial lunar eclipse from southeastern Poland – my homeland, this time. The event, although very short, will be remembered probably forever. Before I will get...
Total solar eclipse 2020 – remote chasing the umbra and a brief explanation how do the webcams work
The total solar eclipse on December 14, 2020, was the last one in the 2nd decade and obviously the first “Twenty Years Solar Eclipse Path Tables” of the XXI century. Most people call this...
The visibility of Venus before the 2020 inferior conjunction
The inferior conjunction of Venus with the Sun happens almost every year. Almost, because in about the 8-year cycle of our neighbor planet she passes the Sun-Earth line 5 times (the synodic cycle counts...
Solar eclipse below the horizon 2019 – the World’s first webcam observation
My third remote observation of the solar eclipse was aimed at the fleeting lunar shadow when the Sun was already below the horizon. Previously I hadn’t had occasion to see a similar effect, as...
The aspect of light reflection in the long-distance observations
This article presents the result of the longest distance observation in my life. Because it was an effect of the light phenomenon, not widely discussed by myself so far I decided to develop this topic, because of its influence on the far realing views during some specified conditions (tick haze trapped in low-level of the […]
Horizontal visibility as the main factor of long-distance observations, part 1 – weather, astronomical and optical elements
This article is sort of a continuation of issues related to light scattering in the Earth’s atmosphere as well as haze presence. These subjects are closely associated with each other, so some stuff presented...
What is a light transition? What examples of it can we see?
Light is omnipresent in the Universe and the environment. This is electromagnetic radiation, that can be detected by the human eye. I have written more about the light and the ways of measurement in this...
Light scattering in the Earth’s atmosphere part 3 – clouds, haze and surface
Previously I have described the light scattering mechanism on the smallest particles of the Earth’s atmosphere, where mainly the Rayleigh Scattering plays a role. Now is the time to round off this whole article...
Light scattering in the Earth’s atmosphere part 2 – why is the sky blue and how the sky colour change?
When we ask ourselves why the sky is blue we can think about the most important type of light scattering in the Earth’s atmosphere. This is Rayleigh scattering. I was writing about this type...
Tenerife and the night sky
Visiting Tenerife, the largest of the Canary Islands was one of the best adventures. After several days, when I could scout this picturesque place I spent one night above the unique low-level clouds. It...
Watching the sky with Krosno branch of Polish Society of Amateur Astronomers (PTMA)
In this article, I would like to describe my a few years of adventures in the Krosno branch of the Polish Society of Amateur Astronomers, where I could develop my noble hobby. Except for...
Total solar eclipse vizualisation on Google Earth, part 2
<<< Read the 1st part of The solar eclipse visualization on Google Earth In the 1st part of this article, I showed you how to create the “umbra” in Scribble Maps and use it...
