This achromatic Baader SunDancer II Telecentric System TZ-3Sfrom Baader SunDancer II Telecentric System TZ-3Sis designed for the entire visible spectrum and can therefore not only be used on H-alpha systems, but also replace a Barlow lens. While the magnification factor of a Barlow lens changes with its distance from an eyepiece or camera (zoom eyepieces are also based on this principle), the magnification factor and image quality of the TZ-3 do not change, even if the new focal point deviates very significantly from the working distance of the optical design (65mm).

The achromatic SunDancer II TZ-3S illuminates an image circle of 35mm at a distance of 65mm from the base body, ideal for the small sensors of modern, fast planetary cameras that require high magnification for photographing the moon and planets. The contrast is better than with simple Barlows or the eyepiece projection often used for high magnifications. With the 3x telecentric system, the high magnifications which are necessary for visual observations can also be achieved with long focal length orthoscopic eyepieces. The interpupillary distance of the eyepieces used does not change either.

The connection on the telescope side is made via a dual 1.25"/2" nosepiece with safety kerfs (these prevent tilting due to an incorrectly positioned safety groove and at the same time provide a secure hold). On the camera side, the T-2 thread provides a tilt-proof, fixed connection, even to heavy cameras or to T-2 eyepiece clamps. For the T-2 thread, adapter rings are available for almost all common connection systems (e.g. M48 / 2"/ M68).

Related Questions and Answers

Q: 1. Are the batteries for Crane 3 Lab compatible with Crane 3S? Look the same.

A: yes the batteries are the same

Q: 2. Is it compatible with Canon R6?

A: Yes

Q: 3. Will the software become obsolete and make the crane 3s unusable?

A: The Zhiyun CRANE 3S-E Handheld Stabilizer can operate to a degree without the smartphone application.

Q: 4. Can it be programmed to automatically take panorama shots with focus stacking ?

A: Focus stacking is not supported with the Zhiyun Crane 3S. The App allows for 180deg, 330deg and a 3x3 array of stills in panorama mode.

Q: 5. Do you need the Transmount Image Transmission System to transmit video? Or can you also monitor & control the gimbal with just your smartphone?

A: The Zhiyun-Tech Transmount Image Transmission Receiver for WEEBILL-S/CRANE 3S/2S (BH #ZHGMBCOV2) is not included in the box with this model.

Q: 6. Is this compatible with a Canon XF605? If so, am able to control camera functions (record, zoom, ect) with the gimbal?

A: The Zhiyun-Tech CRANE 3S Handheld Stabilizer does not list the Canon XF605 as compatible.

Q: 7. Would this work on a platypod. I'm concerned that the tightening knob would not allow it to sit flat or be hard to turn?

A: Unfortunately, this would not work with the Platypod. In our testing the tightening knob does not allow the head to sit flat and cannot be tightened fully.

Q: 8. Does it charge the camera?

A: Yes, the Insta360 Quick Reader for GO3/3S also doubles as a charger for the Insta360 GO 3 or 3S when it's plugged into a power supply.

Q: 9. Is this compatible with the Crane 2 focus motor?

A: It is not. The Crane 2 Focus Motor is only compatible with the Crane 2. For this system you will need BH #ZHGMBC528E instead. https://bhpho.to/3bwAQmn

Q: 10. Will the focus/zoom motors from the Crane 3 lab work with the 3s?

A: While we have not yet been able to perform a hands on test with the Crane 3S, it appears that the focus/zoom motors use the same kind of protocol and therefore should work, but we cannot confirm that at this time.
