TTS-Optics 120 mm 90° binoculars with 1.25" interchangeable eyepieces

The TSBSA120-90 are binoculars for day and night

Observe an animal at the edge of the forest, a climber in the steep face or stars and planets. The TSBSA large binoculars are a real all-rounder and offer clear and sharp images even at dusk. The lenses of the TSBSA binoculars have telescope quality! Magnifications of up to 100x are possible.

Easy and accurate focusing

The focus adjustment feels precise and high quality - and that´s exactly what it is. The two separate helical receptacles can be adjusted softly and precisely, for crisp, sharp viewing experiences. The setting on each page also automatically adjusts the diopter compensation.

The magnesium housing

In order to keep the large binoculars light, the body was made of magnesium. The binoculars are only 7.45 kg light, incl. tripod holder.

Interchangeable eyepieces - set the magnification yourself

All common 1.25" eyepieces can be used. The eyepieces are interchangeable at any time. Adjust the magnification to the target object. Two zoom eyepieces with stepless magnification are a useful addition if you don´t want to have too many eyepieces.. Two 18 mm flatfield eyepieces are included in the scope of delivery. With 65° field of view they are strong wide-angle eyepieces and the flatfield design gives you very good sharpness right to the edge.

Filter thread for more contrast

Something few binoculars offer. In this model, you can use your own 1.25 filters on the eyepieces to make observation even better and more interesting. How about city light filters, for example, to amplify astronomical nebulae? Or with grey filters for moon observation?

Optimum illumination thanks to oversized prisms

Large prisms allow 100% illumination when using standard 1.25" eyepieces. The transmission, colour correction and contrast are on a par with much more expensive glasses.

90° view - perfect for hobby astronomers

A pleasant posture is just as important for observation as good mechanics. The eyepieces in a 90° view are particularly suitable for sky observers who like to observe objects close to the zenith. In contrast to a 45° view, you do not have to dislocate yourself with very high objects. It is a fact: who observes pleasantly, recognizes also more.

First Light mit dem TSBSA100-90 Binokular

"For a first test, I pointed the binocular at the moon and some stars: The sight exceeded my expectations, with 32mm and 20mm (each TV Plössl) the sight is particularly good. I didn´t use the attached eyepieces. The moon appears very clear and like 3D, an effect I don´t know from my 6" refractor with binocular approach. The yellow color fringing does not interfere. Structures at the terminator of the almost full moon are very sharp. At a higher magnification (up to 115x) the image becomes darker and less contrasting as expected and a violet color fringing is added, which in my opinion is completely ok for a non-APO. The colour of the stars is reproduced very well, especially at low magnification. The price-performance ratio of the binoculars is very good, also because of the very good workmanship, which I would rather expect from a more expensive binocular and because I have the possibility to change the eyepieces."

Question:
Can zoom eyepieces be used on these binoculars???

Answer from Teleskop-Service:
Yes, the working distance is suitable for zoom eyepieces. We particularly recommend the HRZ. This zoom offers good view.
