If you appreciate my work and want to get into astrophotography too, I strongly recommend the e-book written by Bastien Foucher. Indeed, his practical advices and expertise allowed me to progress and discover new techniques for constantly improved results.
The most spectacular images are not necessarily those taken with the most specialized equipment, even in deep skies. For my part, I think my best achievements have been captured by my old Canon 6D.
If you would like a preview of the book or more information, feel free to follow this link (only available in French for the moment):
