A very simple design, with a flat platform on the ground, with a box on top of it where the scope is mounted. The three major variants of the altazimuth mount are:ĭobsonian The 'Dob' was developed by John Dobson in the 1960's. However the computerized mounts can be used for deep sky astrophotography if you are using a digital imager and keep your exposures short. These mounts are fine for visual use, especially when using a short focal length telescope, but they are not very good for astrophotography except for planetary/lunar imaging. Due to their simplicity they are cheaper (except in hi-tech computerized models). They move in two directions for tracking, altitude (up/down) and azimuth (side to side) thus the name, AltAzimuth. These are the simplest, most basic styles of telescope mounts.
There are basically two types of telescope mounts though each has different variants. However for astrophotography purposes the mount needs to be more stable and be able to track the object you are trying image accurately. We will then explore the particular features which are important for astrophotography.Ī telescope mount's purpose, in simple terms, is to hold the telescope firmly and to provide a way to smoothly move the telescope.
Once again we will start with the basics of telescope mounts and the advantages and disadvantages of each type.
