For observing, the tube weight should not exceed the mount’s maximum payload. For a stable photographic combination of tube and mount, it is wise to also pay attention to the tube length and dimension, where appropriate, to stay below the maximum load, as the leverage effect on the mount must be taken into account.
The scales of the RA and DEC axes of equatorial mounts. With more expensive mounts, the setting circles are also suitable for locating objects using the equatorial coordinate system.
Optical telescopic tubes are usually connected to the telescope using an adapted dovetail bar. This makes it possible to quickly set up and take down the telescope.
An object can be selected using a hand-control box, the telescope will be automatically directed to it, and the object is positioned in the field of view.
