Wesley's Tool-Box

This year's lunar eclipse was a long one, with the added bonus of having Uranus occulted by the Moon during the totality. This doesn't happen very often, and the next one is supposedly more than 200 years away. So I prepared my equipment and observed the progress at a good spot near home.

I did have some difficulties during the 4-hour session, as one camera battery couldn't last that long and dew was building up on the lens after 9 PM. But using a camera with a powerful zoom worked great for capturing the Uranus approaching and then hiding behind the Moon. It was literally a once-in-a-lifetime observation.

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.

With the red planet coming close again after two years, it gave me another good opportunity to take a detailed look of the surface using my equipment. The Nikon P1000 has been working well for me these days, so I pointed its lens to the sky around midnight to capture the photos. Although the total session lasted less than an hour, I got satisfactory results.

Last time the Mars was close, I photographed the eastern hemisphere. This time I got to see the western hemisphere, which has the famous features like Olympus Mons and Valles Marineris, one of the biggest examples of mountain and canyon in the solar system, respectively. Also, I got to see the polar ice caps on Planum Australe for the first time, a highlight of the otherwise reddish, 45-pixel wide (22.6" apparent) disc of the planet.

This summer, Saturn is easily found near the bright Jupiter in the southern night sky. It's been nearly two years since I took a good look at it, so I took out my P1000 and shot some photos of it. It's amazing how well the rings come out with this superzoom camera after some post-processing.

I'm getting the hang of photographing the planets with P1000 after some practice. Jupiter sets below the horizon too early these days, so I targeted Saturn and Mars. Using the Moon as the reference for the manual focus (actual setting seems to vary up to ten dial ticks by the daily conditions) and turning off the vibration reduction (better to let the tripod stabilize on its own), I was able to take several photos for processing. Discernible in the results are the prominent differences in the surface colours of Mars, as well as the Cassini Division on the rings of Saturn.
