This GOTO telescope with very good optics was produced at an affordable price point. The tripod and mount are undersized, so it is sensitive to wind and takes a while for vibrations to settle down. At 4″ in diameter it has sufficient light-gathering ability to see a great many objects, yet it is not very sensitive to atmospheric turbulence that can ruin the views in larger telescopes. It has a few too many parts to be considered grab-and-go, but it is quite light and easy to set up.

This featherweight travel telescope has quite acceptable optics on a very shaky mount. It packs into the included small backpack. Lenses are plastic, the finderscope is not necessary, and the whole thing threatens to blow away if there is some wind, but it is quite usable as a telescope.

This telescope is well suited for high magnifications when viewing the moon and planets. Focus is easy and the mount is surprisingly stable. It’s a great grab-and-go telescope for the brighter objects.

This unusual pick-up-and-go elbow telescope is easy to transport and a joy to use.  It’s a wide-field right-angle refractor married to a Dobsonian mount.  The objective is almost 5” across, and it has a single fixed eyepiece.  Telescopes don’t get much simpler than this, nor easier to use.  Pull out the eyepiece for coarse focus, twist it for fine focus control.  The field of view is about one quarter that of 7×50 binoculars and rivals that of many larger telescopes.  The stars are crisp, with very little distortion until the edge of the view. 

Unlike all other designs of telescopes, the eyepiece always remains at the same height no matter where the telescope is pointed. The mount can be placed on a picnic table or attached to the optional tripod. Very suitable as a grab-and-go during winter. Highly recommended.
