18 years of RIPE and IETF meetings

In the 18 years from 2002 to 2019 I attended 9 RIPE meetings, 1 LACNIC meeting and 16 IETF meetings in 20 cities and 10 countries on 3 continents. Here are a few random photos from each meeting or city.

You may notice camera improvements over time. 😃

Comet hunting

Earlier this week, I read that there's a comet that's visible. It's called C/2020 F3 (NEOWISE), but I'll call it Neowise for short, after the space telescope that found it.

More comet hunting

It was reasonably clear again yesterday night, so I tried shooting the comet from my balcony, which worked pretty well despite the two streetlights illuminating the camera:

I then went to a dark place just outside the city, and took this shot:

The blue in the first photo is probably due to the auto white balance taking some foreground that I cropped out into account. Soon after I started shooting, mist came rolling in, which may explain that the detail wasn't better in the second shot.

Apart from that, the comet head clearly looks greenish here (click on the second photo to see a larger version), and the comet has moved a surprising distance between the first shot at 0:09 and the second at 1:37.

Same 105 mm f/2.8 macro lens wide open, ISO 1000 for the first shot, ISO 1600 for the second.
