Science in Astrophotography

In astrophotography we always talk about travelling to dark skies, however not everyone has the opportunity to move away from the big cities. In those cases, it is important to know that we can still do astrophotography! All we have to do is modify our workflows and use different techniques. In this episode, I describe the different options of light pollution filters that we can use to help us doing astrophotography under bright city skies.

December came and with it one of the most awaited astronomical events of the year, the arrival of comet 46P/Wirtanen. It has been quite a while now since the last comet visible with the naked-eye and because of that, everyone is getting very excited about it. However, the images that we are already seeing are showing us a comet quite unusual, without its typical long tail and showing us a green colour. Why is the comet green? Where is its tail? In this episode, not only I will talk about how to photograph it, but I will talk about the science behind the way it looks.

December is here and it is time to talk about the astronomical events that we will see until the end of the year. This week’s episode summarises the main events and objects of the night sky that we will be able to see and photograph from the North and South Hemispheres, including additional information on the science behind them. We talk about comets, meteor showers and stellar clusters, with emphasis on what equipment we will need to photograph them.

Should I update my camera? What lens should I buy? Should I invest on a new DSLR or a CMOS or a CCD? Should | get a star tracker or a telescope? If you are asking yourself some of these questions, or similar, now that Christmas is approaching, then this is your podcast. In this episode, | walk you through the different accessories of the astrophotography equipment, from basic to advance levels alike, to help you decide what should be your next step on your photography adventure.

November is here bringing with it the winter night sky. This week’s episode summarises the main events and objects of the night sky that we will be able to see and photograph from the North and South Hemispheres. We talk about comets, meteor showers, galaxies and nebulae, with emphasis on what equipment we will need to photograph them.

This week we will talk about how to photograph the Sun using either DSLR or dedicated CMOS cameras and telescopes. I talk about what things we will be able to see depending on our set up and briefly describe the science behind all those features. I also mention very briefly some of the techniques used to capture the data.

In this week’s episode, we are celebrating the first anniversary of the announcement of the first object detected by telescopes and gravitational waves simultaneously. This incredible discovery has kicked off a new era in the world of astrophysics and in this podcast, I will talk to you in a clear and simple way about how the discovery happened and why it is a game changer for astrophysics.

In this episode, I talk about how to know if the International Space Station (ISS) will be visible from our location and how to photograph it either with a wide-angle lens or with a telescope to be able to capture its shape. I also talk about planning observations of the ISS while transiting the sun or the moon. Finally, in the podcast I talk about what an Iridium flare is and how to capture it, and how to spot geostationary satellites.

Have you ever wonder what it would be to be part of a large scientific project? In this podcast I will explain how you can use your astrophotography shots using DSLRs or CCDs, to join hundreds of astrophotographers like you to study variable stars.

September is coming to an end and October comes with a brand new night sky. This week’s episode summarises the main events and objects of the night sky that we will be able to see and photograph from the North and South Hemispheres. We talk about comets, meteor showers, galaxies and nebulae, as well as how their properties can affect the way we photograph them.
