Science in Astrophotography

As it is now tradition every month, this week’s episode summarises the main events and objects of the night sky that we will be able to see from the North and South Hemispheres during March. As always, the episode includes tips on how to photograph them as well as additional information on the science behind them. We talk about planets, the moon, galaxies and stellar clusters.

This week I bring you my top 5 list of weather apps to help you plan our observing nights knowing if the sky is going to be clear or covered. Each app has its pros and cons, but after years testing different options, these are the apps that give me the best results and I consider them the most reliable for my planning. I hope they can be useful for you as well.

The effects of the atmosphere in astrophotography

If you have ever wondered why it is sometimes difficult to capture the Moon when it is close to the horizon or why some nights without clouds you get disappointing results compared to others, then this will be a very special episode for you. This week I talk about how the airmass or the seeing can affect our images. I also talk about the lucky imaging technique that help us counteract these effects and give us more sharper images of the moon and planets.

The proper calibration of our RAW images, is a really important stage of the acquisition of astronomical images. In this episode I describe each of the different types of calibrating images, why they are useful and how we need to proceed to take them and apply them.
