Advantages of the TS Gigant compared with binocular viewers:

The Gigant 152mm is suitable even for use with 2" eyepieces, a feat that almost no binoviewer can offer. As a result you can view a particularly large area of the sky - up to about 2.3° in diameter! At the same time the image is twice as bright as that of a binoviewer for any given exit pupil diameter: Normal binoviewers split the light collected by a single objective and direct it to two separate eyepieces. As a result each eyepiece will only get half the light. Not so with the Gigant, which has a separate objective for each eyepiece!

Semi-APO Triplet Objective Lenses:

The Gigant 152 is built around a pair of 152mm triplet semi apo lenses with 824mm focal length. Colour correction is noticeably better than that of a classical achromatic objective, allowing for high magnifications without distracting false colour. The objective cells are adjustable.

The Gigant has a pair of helical focusers for 2" eyepieces. The focusers are aligned at a comfortable 45° angle, allowing for comfortable observing of objects far above the horizon. The prisms are large enough for good illumination of the full field of view. The individual eyepieces are focused by rotating. Interpupillary distance is freely adjustable from 62mm to 76mm.
