Tracking the ISS with Nikon P1000

Int'l Space Station captured by Nikon P1000 on October 27, 2018

Next target I've been eyeing to take some photos of using the powerful zoom provided by the Nikon CoolPix P1000 camera was the International Space Station. Although it's a fast-moving target, I have experience with other equipment and the P1000's zoom should be sufficient enough to let me distinguish major features under ideal conditions, similar to the photos I took using a telescope. One such pass happened on October 26, coming in as close as 410km, but the thick clouds prevented me from taking the shots. Luckily, a slightly worse backup opportunity (closest approach of 572km) happened just a day after and I made the best of it - what you see above is the result.

iPhone 5S was used to help track the ISS as the P1000 took photos

As it was the case with SX50 HS, tracking the station is nearly impossible with just the integrated screens on the camera. So I enlisted the help of an iPhone mounted on the camera's hot shoe. It was very effective and I was able to take an unbroken sequence of the space station for more than a minute, until it went out of my view. If you want to see the whole thing, watch the video below. I think it was good for a first try with a new camera. More opportunities are to follow in the coming weeks, so stay tuned.

The Nikon P1000 Moon shot

Due to the extreme optical zoom, Nikon P1000 actually has a dedicated "Moon Mode" in the scene selection wheel to let you photograph the Moon. However, I wanted to get used to the manual operation of the camera and so I took some photos of the Moon under manual mode. This one looked to be the best one so far, with tiny craters easily visible.

The Moon is currently 1,775 arc seconds wide, while it was 3,462 pixels wide on the photo. This is just a hair wider than the height of a photo that P1000 takes (3,456 pixels). This translates to 0.513 arc seconds per pixel resolution for the camera at maximum zoom.

Century's longest total lunar eclipse and Mars

Those living in Korea was able to see the second total lunar eclipse of the year, following the one in January 31. I had multiple reasons to watch this eclipse. There wasn’t going to be another total lunar eclipse visible in Korea for nearly three years (next one is on May 26, 2021). Also, Mars was just past the opposition, shining bright next to the Moon and forming an interesting celestial pair. Finally, the eclipse was billed as the longest in the century, including more than 103 minutes of totality.

Weather cooperated well, and I was able to both observe and record the progress without a hitch. The result is the composite photo above. It was the first time my newly acquired Sony SEL55210 lens was put to use for astrophotography and it performed adequately.

Celine witnesses her first lunar eclipse after waking up early

One minor disappointment was that the Moon was to set below the horizon during the middle of the totality. So I focused on watching it comfortably in the house with my daughter instead of trying to see through every moment. In fact, it was first such eclipse visible through the southerly window since 2011, enabling Celine to see the phenomenon for the first time. She was impressed with how the full Moon progressively got dimmer from the left corner, eventually becoming red from the Earth’s shadow. Next time, I hope I can show her the comeback part.
