The swivel range
The Porta offers a large swivel range. You can easily reach any position, from the horizon to the zenith. This is exactly what makes the mount so versatile.
Especially when observing objects high above our heads, the Porta has an advantage. Many azimuthal mounts, but also spherical and tilting heads, do not allow an upward tilt, because the device used to hit the tripod legs. This is not a problem with the Porta.

The Porta´s Fine Adjustment
The Porta mount offers two adjustment options. You have an adjustable friction clutch. So you can swivel it freely, just like with a normal ball or tilt head. This allows you to reach your goal very quickly.
In addition, you have a micro fine adjustment for both axes. This allows you to accurately centre the target even at high magnification, or to very accurately track slow-moving targets.

A handy storage option
The Porta also offers a practical storage option between the legs of the field tripod. This gives you a good place for extra magnification, adapters, etc.

The advantages of the Porta at a glance
