I’ve heard on more than one occasion “the mount is the most important part of your astrophotography setup.” That’s usually followed with “focus more on the mount than the telescope” when it comes to putting together your imaging rig. Without a firm foundation a house is doomed to collapse. These suggestions and recommendations are sound.
It’s important to choose a mount and tripod that are stable, rigid, precise in their tracking abilities, rated to accept the total weight you plan to place on them during your imaging sessions and well tested with accessible and repeatable results. When it comes to stability and tracking for astrophotography your mount had better perform as advertised or your images will suffer no matter how much money you pour into your telescope and imaging cameras.
