Chapter 3 and more Aladin

Chapter 3 was a long one, but they saved the best to last with the Chapter 3 activities being more tinkering in Aladin.

Aladin uses FITS files which contain a lot of information regarding the photo. So, when you load a FITS file into Aladin you can see, using scientific notation (hours, minutes, etc.) where you are in the sky. Aladin also uses layers (like Photoshop) which lets you blend images. You can also create fake colour images.

Taking three layers (each image being photographed with a different type of light capturing camera):

You can apply an RGB to each of the layers to get a fake coloured image:

Having tinkered with it a bit more, Aladin seems kinda low on features, but that might just be ignorance on my part.

To Chapter 4 and beyond!
