TS-Optics Premium Zoom Eyepiece 7.2 mm to 21.5 mm - 1.25"
The HRZ zoom eyepiece from TS offers sharpness close to an HR ocular with fixed focal length. It has a zoom range from 7.2 mm to 21.5 mm. During design process, the developer attached importance on creating a fully functionable zoom eyepiece with great optical and mechanical performance.

Zoom function: stepless from low to high magnification
Zoom eyepieces offer particularly convenient observing, as one eyepiece covers the same magnifications as a number of fixed focal length eyepieces. You can start at low magnification and then easily increase the magnification, without having to change eyepieces. And you keep the object in view during the entire process. It could not be more convenient.

It is also extremely practical to be able to increase magnification step-lessly from low to high. It allows you to easily find the optimum magnification for the particular astronomical object being observed and for the current seeing conditions.

And so you can keep a firm grip on it in the night, the Premium zoom has a non-slip ring for the adjustment of the magnification. An arrow and engraved numbers mean you always know which focal length you have selected.

Optical quality - exceptional sharpness
As soon as you have a planet or deep-sky object in the field of view, you will notice one thing - the fantastic image sharpness. The Premium zoom eyepiece has a special optical design which provides striking contrast and excellent sharpness, right out to the edge of the field of view. The optical quality really is comparable to that of a fixed focal length eyepiece.

Contrast Power - stray light baffles
The eyepiece has been designed with blackened lens edges and baffles to guard against unwanted stray light. This improves the contrast and hence your observing.

Eyecup screws out in three steps
The height of the rubber eyecup can be adjusted to three settings. Depending on your personal eyesight, you can easily decide whether to leave the eyecup in the normal position or in one of the three higher settings. Looking through the eyepiece will not affect the eyecup´s position.

Particularly helpful with modern refractors
Especially convenient is the purchase for owners of a modern ED refractor with a focal ratio of f/7 or similar. Here, the zoom will offer exit pupils between 3 mm and 1 mm - the common range for viewing galaxies, planetary nebulae and man star clusters. Together with a 2x Barlow lens, you also get the range from 1.5 and 0.5 mm - high and highest magnifications common for viewing planets and the moon. The zoom is helpful for adapting the magnification to the seeing, allowing to see the finest details possible at time you observe.
