Nikon P1000 catches the ISS transiting the Moon

ISS transits the Moon on January 22, 2019 (18% size)

Orbital prediction indicated that the ISS would be seen passing in front of the Full Moon at a place about 20km away from home. Thanks to the Moon being at an altitude of more than 60 degrees, the space station was to pass close to the observer with an angular size of nearly one degree (58.7"). It seemed be a good opportunity for using the 7-frame full resolution burst mode of the Nikon P1000 camera, so I drove to the observation spot despite the cold weather (-4°C) and inconvenient time (3 AM).

There was about one second of difference in the transit time prediction between different tools, and the burst mode could only take the seven photos in a span of a single second. So I took a guess as to when to press the shutter button and hoped for the best. Luckily, I did manage to catch three frames out of it, as you can see here. The results were sharp and large enough to make out the individual solar panels and modules, proving the capabilities of the P1000's telephoto optics.

Partial Solar Eclipse of January 2019

Solar Eclipse of January 6, 2019 seen in 2-minute intervals
Eclipse animated at 10min/sec

Good eclipses come by every few years, with lunar ones somewhat more often than solar ones where I live. The last solar eclipse I photographed was back in 2012, and I missed the one on 2016. As if to make up for that, two occurrences would be visible in 2019, with the first one taking place yesterday and the next one the day after Christmas. A better camera and filter than 7 years ago was set up on a window to capture the phenomenon. Strips of cloud interfered at the beginning, and the adjacent apartment building blocked the view for a few minutes towards the end. But the session went quite well otherwise.

Zooming to 2000mm, I could see the jagged outer edges of the Moon obscuring the Sun. But for the purposes of creating a progressive composite and animation, the extreme zoom turned out to be a bit of a waste as I had to reduce the size to 4% and 8% of the original, respectively. I'll need to consider this the next time I take eclipse photos.

Thanks to the eclipse happening in the early Sunday morning, everyone in the family was able to witness the event together. I let the kids follow the progression of the eclipse though the camera's viewfinder, and they were able to take an eclipse photo as well.

Alternately, I let them know that the eclipse could also be seen indirectly by using a pinhole. Kids had fun poking holes on pieces of paper to see the crescent shapes shining on a wall. I hope the next observation goes just as well and interesting.

Watching a rocket launch: Nuri(KSLV-II) TLV

Nuri TLV at T+34s - soaring into space with "대한민국" (Republic of Korea) on the right-hand side

Republic of Korea (South Korea) has been developing a fully indigenous launch vehicle called Nuri, also known as KSLV-II, after the joint development of KSLV-I (Naro) with Russia was complete five years ago. The key piece of this technology is the KARI 75-Ton rocket engine, of which four of them would be used on the first stage and one on the second stage. To see that the engine actually can launch itself, a single-engine single-stage version of the rocket, called TLV (Test Launch Vehicle) was created. It was launched successfully today at 16:00 sharp, Korean Standard Time, and I was able to record it fully, as you can see here.

Originally slated for October 25, the launch was delayed to today, November 28, 2018. But I was still able to take half a day off from work to see this for myself. I headed to a nice lookout spot in Naenaro Island, only about 7km from the launch site, which was not quite as obscure as I initially thought - there were already dozens of people there when I arrived, including a TV crew. Luckily, there was still a spot for me to set up my Nikon P1000 camera for observation and recording.

The distance was too far for the naked eye to properly see the rocket. Only the fiery dot could be seen rising up to the sky. But the P1000's powerful zoom was more than good enough to capture the sight in its full glory. I was able to track the rocket with relative ease using the Olympus EE-1 dot sight attached to the camera. For the full video recording, see below.

Nikon P1000 observes ISS-Sun transit

Nikon CoolPix P1000 observes the Sun next to Celestron NexStar 6SE telescope

Encouraged with the results from the previous observation, I took the Nikon P1000 outside during the day to take the photos of the ISS crossing in front of the Sun. Last time I was able to see the transit at home was three and a half years ago. I also got my Celestron telescope out as a backup in case any one of the equipment failed to record the phenomenon. The camera needed a solar filter like the telescope, so I bought an ND100000 glass filter online for US$40 that provided the same amount of light reduction.

Although the P1000 has burst mode, it can only take seven photos in a span of a second. The window of opportunity was too narrow, so instead of taking the risk I used the 4K 30fps video capability instead. It would sacrifice image quality, but I was sure to get the shot if the frame and focus were right. And sure enough, the transit was captured successfully as you see above.

The result may not be not quite as sharp as using a telescope, but much of the features of the space station were distinguishable. Perhaps I should try the burst mode the next time I get the opportunity to see if that makes a difference.
