This text is somewhat the continuation of the previous one, tailored for the most unique celestial events or group of celestial events, which will occur in the 2021-2030 decade. This time you will read about 10 of the best occurrences in the sky within the next 20 years. Some of the astronomical events described in … Read more
Recently we have entered the new decade 2021-2030. This is a good time to take a look at what major astronomical events will occur throughout this time. I don’t mean typical celestial events, as known from a vast majority of astronomical calendars issued usually on a yearly basis. I would like to take a deep … Read more
I would like to introduce the new tool, whose goal is to extract the ephemeris data from the Astropixels.com service. Before I start to describe the major features of my program I would express a big thanks to Fred Espenak the author of this platform. Fred Espenak is already a retired American astrophysicist, whom we … Read more
The summary of my amateur test with a Sigma 150-600mm DG OS Contemporary lens and two teleconverters TC-1401 and TC-2001 includes the astrophotography section. I wanted to check this lens in terms of its ability to capture celestial objects. The fundamental difference between celestial objects and terrestrial objects is, that these first are in motion, … Read more
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 854 days exactly), making a peculiar pentagram, comprised of 5 petals. Every petal corresponds to the individual character of the inferior … Read more
This is the second part of the article, explaining the great Venus orbit cycle, which repeats on average every 3159-3160 years. Reminding the basic mechanism it’s exactly 395 8-year cycles, where the planet back pretty much to the same place at the same time in the Sky, except the situation, where this moment in its … Read more
The biggest celestial event in April 2020 was definitely the meeting between our closest planet Venus and one of the most renowned open star clusters – the Pleiades. The phenomenon was interesting due to its rarity. Throughout our life it will happen every 8 years, but what’s next? This article brings you not only the … Read more
In this short post, I would like to share with you my ideas, on how can we use the Hydrogen-alpha filter for solar observations during exceptional situations. The situations, that I am going to take into account are mostly solar eclipses, but also internal planet transits. We have less than 2 months to Mercury transit … Read more
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 was a fantastic experience because I have not seen that pristine sky before. The day, when I set my observation place … Read more
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 my activities, I want to show the best and the most unique observations made by members of this society in the … Read more
13 and 5 years ago we could witness an unusual occurrence when an inferior planet crossed the solar disk. The transit of Venus is a very rare celestial phenomenon, which occurs usually twice in the span of a little bit more than 1 century. I said twice because between first and second transit is approximately … Read more
