Month: October 2022

Solar eclipse

October 2022 offered several spectacular astronomical events in the Solar system. Recently I captured the transit of the moon Io across Jupiter and on the 25th a partial solar eclipse occurred. I was ready, the forecast was optimistic, but the clouds were still blocking the sun. Fortunately, a small gap between the clouds occurred and the sun for visible for a short moment. I didn’t hesitate a bit and focused my solar telescope, adjusted the tilter, and the pressure tuner. As soon as the picture acquisition started, the clouds rolled in again. In total, I managed to store only 876 pictures, so I selected 35% best ones and stacked them together.

Later on, the clouds cleared completely, so I got the opportunity to capture the sun properly.

This year was a special occasion to observe or photograph Jupiter. The biggest planet in our Solar system got very close to Earth. In fact, it was the closest in several decades. Such events force me to take an action. I had to wait for a cloudless night and took my biggest telescope out. Well, I must admit that the opportunity of Jupiter’s opposition is great but more important than the distance between the Earth and the observed planet is the quality of seeing. The light started the journey on Sun, then traveled 778 million km to Jupiter, got reflected and traveled 367 million km back to Earth, and got spoiled in the last 100 km when passing through the thick Erth’s atmosphere.

On 19.10.2022 I was extremely lucky because Jupiter’s moon Io was transiting and creating the eclipse. Moreover, the giant red spot was visible simultaneously. I captured a few shots and got the idea to capture more of them and compose a video. In total, I was photographing the event for nearly one hour and made 15 frames out of it. You can see how quickly Jupiter spins. One day on Jupiter takes only 9 hours and 55 minutes.

IC1396 Elephant Trunk Nebula

Elephant Trunk Nebula is my favorite nebula in the constellation Cepheus. I photographed it many times using many different telescopes. The focal length was either too short or too long. Now I tried a focal length of 414 mm and an APS-C sensor, to frame it. I photographed this nebula for two nights, the total integration time is nearly 11 hours.
