TSQ-100ED Quadruplet Apo with permanently built-in field correction
The 100 mm f/5.8 quadruplet of the TS Imaging Star line is highly appreciated by astrophotographers. The telescope is an interesting alternative to the Takahashi FSQ-106ED. Due to the air-spaced FPL53 objective, the image is free from chromatic aberration and provides outstanding contrast. Through the integrated corrector the field is perfectly flattened. You will get perfect stars in the field right from the beginning, without the exhausting search for correctors and the right distance.

Despite the apo was optimized for astrophotography, it will offer very good performance also visually. The stars are pinpoint and are imaged without chromatic correction. The image stays sharp and contrasty up to 300x magnification.

The photographic 4" rack&pinion focuser:
The CNC focuser is optimized for photography and can handle a payload of up to 8 kg. The travel of the drawtube is carried out via rack and pinion. The construction of the focuser is similar to the Starlight Feather Touch and the mechanical stability comes very close to that of the Starlight Feather Touch. In addition to 2" and 1.25" receptacles, an M78x1 thread is also available for screw adaptations. Suitable adapters, e.g. for the M68x1 thread, are of course available.

Features and advantages:
Excellent FPL53 triplet objective (glass from Ohara, Japan)
Integrated flattener with factory-set optimized distance to the objective for optimal sharpness in the field
4" CNC rack and pinion focuser with male M82x1 connection thread - payload up to 6 kg
The system is free from annoying reflections
Objective and corrector are adjustable - but are already delivered optimally adjusted
Each quadruplet apo is checked before shipping and the optical system is tested


A first-class apochromat for astrophotography:
[[kein Bild]]Our goal was achieving imaging quality on the axis AND in the field without compromises, and also without additional flattener or correctors. The corrector has to be built-in permanently and, obviously, in the optimal distance to the objective. This is almost unobtainable by using an optional flattener. Furthermore, the apochromat has to be mechanically solid and easily to adjust. This has been made possible with the flatfield apo.

The focuser has to be stable and, in particular, designed for heavy cameras. With the rack and pinion drive, even heavy accessories can be used. Locking is safely achieved by blocking the adjustment unit.

Connection of cameras with a flange focal distance of 55 mm
The easy way is via the 2" connection. With the TSFA240 adapter you get a T2 connector and with the TSVF230 adapter you get an M48 connector for cameras with larger sensors. You can focus without any problems.

Many amateurs prefer a screw mount. The apo offers a M82x1 male thread for this. We recommend the following adaption for a comfortable focus position. With the adaption you do not go too early on the M48 thread and avoid shadowing with large sensors.
M82i-M68a - length 10 mm
TSVM6840 - M68 extension - length 40 mm
M68i-M48a - length 5 mm

Visual observation through the apo:
The 100 mm Quadruplet is optimized for astrophotography. However, it will also give very good results for visual observation and allows magnifications up to about 250x with good contrast imaging. The tight focus position only allows the use of 1.25" accessories. For a 2" mirror diagonal the focus distance is too short.

This is how we hand over the apo to the star lover:
Every single TSAPO100Q is checked in our technical department before it is put into storage, in order to guarantee a consistently high product quality.
The mechanics are tested, the focuser is adjusted optimally.
The objective is cosmetically checked and cleaned. In addition, it is checked whether all counter screws are correctly tightened. Often these loosen during transport.
The optics are collimated and the result is checked on the optical bench.
Only then are the telescopes transferred to the warehouse and prepared for shipment.


The objective of the 100 mm f/5,8 Imaging Star Quadruplet:


The apochromat uses a classic air-spaced triplet APO objective which is mounted adjustable. The cell is temperature compensated, so even low temperatures will not change the images of the stars. The main glass is FPL53 from Ohara, Japan. All air-to-glass surfaces have the best coating the manufacturer offers.



Optical power on the axis:

The 100 mm quadruplet has not only an excellently corrected field, it also offers true apo performance on the axis. The images correspond to a magnification of around 250x and show the well defined imaging power and the absence of chromatic error of this objective (at left outside of the focus, at right in focus).

Prior to shipping, each 100 mm quadruplet apo is tested in our technical department - thus it is ensured that any optics including yours will eliver maximum performance at the starry sky.

Question:
How do I adapt a camera with a large sensor (full frame size format) without vignetting and without clamping???

Answer from Teleskop-Service:
A too early reduction to the M48 thread would cause vignetting in full frame size format. If you don´t want to go over the 2" receptacle and want to screw everything together, we recommend the following adaptation:
TSVM8230 30 mm extension with M82 thread
FTSM82-M48 transition adapter from M82 to M48
M48a-M48a reverse adapter for the M48 external thread


This gives you a working distance between 55 mm and 105 mm from the M48 thread onwards, depending on the position of the focuser. So you have enough space for filter holders or off-axis guiders.

Of course, you can also screw the TSVM8230s into each other to further shorten the distance.
