Before undertaking the acquisition of deep sky images, it is important to know the different image formats so as not to lose the information which required a lot of effort during the preparation and acquisition of these images. As these images are very dim and require long exposure times, they must be preprocessed to remove thermal noise from the camera, for example. Finally, there will be the presentation of the technique to use to take this type of photo in order to reveal all the details of these dark objects.
Here are the sections that will be presented:
- The different image formats
- Acquisition of images used for preprocessing
- Acquisition of deep sky images
