More info

The supplied erect image diagonal provides an upright, fully corrected image allowing the telescope to be also used for terrestrial observing. The well engineered and easy to use AZ PRONTO Alt-Azimuth mount provides excellent stability and precise control, via its slow motion cables, on both the horizontal (azimuth) and vertical (altitude) axes.

Our Tip

If your interest is terrestrial observation especially birdwatching: Consider a variable polariser filter to allow you to see the feet of wading birds or remove the harsh brightness of leaves....
