Photographing Meteor Showers

Dr Antonio Martin-Carrillo


by Dr Antonio Martin-Carrillo (UCD)

Monday, 19th October 2020 (at 19:30 Irish Summer Time).
Venue: Online Zoom. All welcome, free event.

We are very pleased to announce that Dr Antonio Martin-Carrillo, assistant professor in UCD, will be giving our second talk of the season titled "Photographing Meteor Showers". The talk will be presented using the Zoom video conferencing software and more details on the talk are given below.

Meteor showers are one of the most admired astronomical events every year. Despite having multiple big meteor showers per year, we seem to feel a special attraction for those fast moving flashes of light that seem to appear almost randomly across the sky. Their short duration and fast speeds make them one of the most complex objects to capture in astrophotography. During this talk, I will describe what meteor showers are, what are the main key aspects that differentiate each of the major meteor showers and what are the key aspects to take into account if we want to successfully photograph them. With the great Geminids coming this December with no moon during the night hours, it is a great time to prepare ourselves for what it can be a great show (weather permitting).

Dr Martin-Carrillo is an Assistant Professor at UCD School of Physics where he lectures in astronomy and studies the most violent explosions since the Big Bang, known as Gamma-Ray Bursts. He is also an award-winning astrophotographer that enjoys linking the science behind the astro-images and the techniques to capture them. He owns the Skywonders website.
