The date has come and gone, but the weather was the trickiest part of the event: we had a large cloudy set of systems across much of the northern portion of the USA, though we had almost exactly 30 minutes of clear skies here in Exeter, NH to see the conjunction in all its glory before the clouds then fog took over the evening.
Arrival at the observatory is something I just do, especially when there is an interesting or important event taking place. The day had been solidly overcast, but I was keeping watch on the NOAA GOES-East: Sector View site to see if any clear regions were headed our way. Sure enough, there was a parting in the clouds, about the width of Massachusetts, headed towards us from the southwest. I set up the camera and the telescope in the dome, pointing them both at the correct location… ready for that clear sky moment! Sure enough, the sky did clear!
Setup next to one of the observatory domes, the wide field view was lovely. With good vision, one could easily separate the two planets, Jupiter the brighter of the two, and Saturn the fainter. Here is a photo taken with Nikon D-810 and a AF-S Nikkor 1:3.5-5.6 28-300mm zoom lens, one of my favorite go-to travel lenses. The system was on a stable tripod and time-delay release was used on the shutter to prevent vibrations. The inset image is the telescopic view of the planet pair.
Moving inside the dome, I had the Takahashi FC-125 refractor setup with a Nikon D-810a at prime focus. This stem is very stable, driven on a Paramount Me and protected from the wind. Here are a couple of images taken through the telescope, one long exposure to see Jupiter’s and Saturn’s moons, and another to see some planetary detail. The seeing conditions were atrocious this evening, so no detail was really seen on Jupiter, alas. Saturn’s rings were readily visible, though.
Below is a long exposure image of the scene with all the objects labeled for identification. Those objects labeled “HIP #” are stars that happen to be in the field of view.
Below is an image from within the dome, a view looking along the telescope out the dome aperture where the conjunction was easily seen. This photo was taken with an iPhone. The insert is the telescope’s view. You can also see the incoming clouds from the southwest which were headed to interfere with our observing plan in the very near future.
Not some 10 minutes later, this is what the observatory site looked like: a foggy mess. Only the first quarter moon was visible through the fog and clouds.
