Deep Sky Astrophotography is probably the hardest and most expensive category of astrophotography, but it can result in breathtaking images that resembles what the Hubble telescope shows (with its obvious differences). Sessions often take several nights of gathering data (typically at least 180 minutes of data). Then, stacking and post-processing is mandatory, so there is a lot to learn here.
Strictly speaking, a deep sky object is everything that is outside the Solar System. However, in this page I have decided to include in this category only deep sky objects captured through my telescope, leaving objects within the Solar System as planetary, and deep sky objects captured without a telescope as wide field.
Since there are so many deep sky objects to cover, I will divide it in three sub-categories:
