QUESTAR LIGHT WEIGHT RANGER 3.5
The Ranger 3.5 is an ultra telephoto lens with an effective focal length of 1175mm at f13.2 capable of showing a bicycle spoke one mile distant, and it weighs only 2.6 lbs (1.2 kg). The Questar Ranger 3.5 model is based on the ultimate compact spotting telescope design - the Questar 3-1/2" Questar Field Model. Essentially the Ranger is a simplified version of the Field Model in that the Ranger is provided without the Control Box that would otherwise integrate a Finder and capability to change magnifications quickly. This makes this unit less costly, more compact and lighter weight than our conventional Questar 3-1/2 inch aperture telescopes. It is a good choice for installations and uses and where high resolution is required but where the operator will not need to make quick changes of magnification.
Right: Ranger 3.5 on our optional Camera Cradle PN 53600 and with optional NV Sight attached (109,781 bytes).
The Ranger is provided with a C Mount for attachment of an optional Video Camera, Night Vision Sight, etc. It can accept other optional hardware and eyepieces that will permit a broad range of visual uses, and CCD or film photography too.
The Ranger is the telescope for those who require the same high resolution quality of view as the other Questar 3-1/2" models but do not need the built in features of these Questar telescopes. The simpler design of the Ranger also results in an even more rugged telescope. Particularly good uses of this telescope include video nature observing and surveillance. The instrument can operate with oculars attached form visual uses, CCD or film cameras, or night vision devices. As a visual telescope with the optional Questar Image Erecting Amici Prism the Ranger is a 1,475mm system providing from 46X to 185X views; other optional accessories can extend either range even further.
