Delta Optical - Spotting Scope Titanium 50ED - DO-1920

The Delta Optical Titanium 50 ED is an extremely compact, handy observation telescope with a modern design and very good optical properties. Thanks to its robust design, it is suitable for a wide variety of field observations - both professional and hobby - for nature observation, hunting and even for simple observations in the sky.

As with the larger Titanium 65 ED II telescope model, the very low-dispersion ED-glass lens design has made it possible to significantly reduce chromatic aberrations. This ensures that the image is extremely sharp and high-contrast and that the colours are reproduced with exceptional accuracy. In addition, Ed glass has allowed a short focal length of only 170 mm.

The distinguishing feature of the device is its small size. The Titanium 50 ED telescope is probably the smallest telescope currently produced with a 50 mm lens. It weighs only 500 g and is only 17 cm long.

The telescope is equipped with an eyepiece with a variable focal length for magnifications from 7.5x to 22.5x. The very large exit pupil diameter, reaching up to 6.7 mm, helps to make efficient observations even after dark. The telescope is fully waterproof, and filling its casing with vapour-free nitrogen prevents the optical elements from fogging up from the inside.

The Delta Optical Titanium 50 ED is an extremely well thought-out design. It is particularly suitable for use with astronomical eyepieces in the popular 1.25" mounting standard. To use such an eyepiece, simply turn the mounting ring to the left and, after removing the mounted eyepiece, insert a new eyepiece in its place. Specialized astronomical eyepieces, especially those with a fixed focal length, allow for very large fields of view and extremely sharp images even at the edges.
