Cass. This type of scope is often used for amateur as well as professional imaging applications due to its ruggedness, compactness, and exceptional correction of aberrations. Many such scopes with apertures <100 mm provide great convenience in use and high performance in very portable packages. One design, the 89-mm aperture Questar shown here, is so popular that it has been in production for over fifty years. org/t Astronomical Scopes 39 Richest-Field Form A richest-field(tele)scope (RFT) is defined as one that shows the maximum number of stars within the available field of view.

The borderline between larger monoculars and spotting scopes is indistinct. Most monoculars are constructed for low weight rather than durability. Sealing provisions are minimal. The following table lists a few small models. Company and model M Zeiss Conquest Minox Minoscope Brunton Eterna Deutsche Optik Turmon Celestron 4× 8× 6× 8× 8× Aper. 7° Wgt. org/t 32 Riflescopes and Weapon Sights Riflescopes Small arms, such as rifles, shotguns, and handguns, traditionally have iron sights as aiming references.

8◦ . It is rugged, and has been found to perform well for long-distance nature study as well as for amateur astronomical viewing. org/t Binoculars 23 Giant Mounted Binoculars Impressive performance can be achieved with giant binoculars if the instrument is mounted securely. Objective apertures here are 70 mm to 150 mm and magnifications are 10× to 40×. Some have interchangeable eyepieces, while a few have eyepiece turrets for switching from low to high magnification. This switchable-eyepiece example is a “Border Hawk” from The People’s Republic of China.
