Wesley's Tool-Box

The morning of the new year's day of 2022 was clear, making it great for capturing a nice view. Here's the photo and the video of the observation. I hope everyone have a wonderful year ahead.

Jupiter and Saturn appeared closest to each other in nearly 400 years on the Winter Solstice of 2020. For this Great Conjunction, the two planets were only about 6 arc seconds apart, which meant that I was easily able to take a photo of both in a single frame as you can see here. Some had expected that they might appear as a single dot, but it turned out that Saturn was discernible as a fainter "bump" on the top right side of Jupiter to the naked eyes.

To show the planets and the satellites together, I used varied exposures and then combined the results into a single photo. Titan was the dimmest that I could photograph, and it appears very faintly to the right of Saturn. Interestingly, a star named HIP 99314 was also caught in action between Io and Europa, which means that this conjunction was actually a triple affair.

By the way, I was worried that I wouldn't be able to see the phenomenon in person because it was pretty cloudy throughout the day. Luckily, most of them went away as the Sun set and I was able to take the photos for about an hour until the low-hanging clouds started to block the view. The next closest conjunction happens 60 years later and I'm not sure if I'd be around to see that, so I was glad that the weather decided to cooperate in the last minute.

SpaceX Crew Dragon launched on May 30, 2020, under the mission name DM-2, became the first privately operated spacecraft to reach the Int'l Space Station with a human crew. It is now docked to the Harmony module at the forward end until around August, which makes it possible to be seen when the station is overhead. I made some attempts to photograph it, and these are the first clear results coming from the space station's transit in front of the Sun.

With a distance of 448.9 km, the station would have an angular diameter of 61.6", which made it easier to notice the docked spacecraft in question. You can clearly see the difference when you compare the new photos to the one I took 5 years ago, when another SpaceX spacecraft, the Cargo Dragon, was berthed to the bottom of the Harmony module (and thus not distinguishable from the overhead view) for the CRS-6 mission.

To take these photos, I drove to Hamyang on my Bolt EV. It was about 100 km away from home, but the weather was excellent and I didn't want to waste a good opportunity. I was glad that everything went right. The photo from 5 years ago is an enlarged composite of multiple frames took by an iPhone through a telescope. But it seems that a single photo taken by Nikon P1000 on its own surpasses that with proper focusing, even though the setup is much simpler and lighter. I guess I'll be bringing around the camera to more places.
