TS-Optics REFRACTOR 1.0x Flattener for full sized sensors - M68 connection

The TSFLAT2,5 field corrector corrects the image field of refractor telescopes and allows astrophotography with large sensors and perfect sharpness to the edges.

♦ Full illumination and correction of the image field up to 55 mm sensor diameter.

♦ Suitable for all refractors, requirement is a focuser from 2.5" upwards.

♦ Telescope side adaption via M68x1 ZEISS level thread. Adaptors to other connections are available.

♦ Comfortable working distance between 87 mm and 106 mm, depending on telescope.

♦ Generously dimensioned threads and stable housings - dimensioned also for the adaption of heavy cameras.

♦ Neat matte blackening inside and anti-reflection threads - no reflexes or ghosting.

♦ Comes in plastic case Drehpack 8080.


 

TS Optics 2,5" PHOTOLINE Corrector for APO refractors - large camera sensors suitable up to large format.

With the TSFLAT2, Teleskop Service has created one of the best and most universal correctors for astrophotography with APO refractors. The big TSFLAT2,5 offers the same correction, but with considerably wider illumination.

 

The advantages of the TSFLAT2,5 in overview:

♦ The corrector is screwed to the focuser.
♦ Generous working distance, suitable to all cameras.
♦ Illumination and full correction up to large format.
♦ Usable with all apos with focusers from 2.5".
 

Adaption to the refractor:

The TSFLAT2,5 is attached to the refractor via the male M68x1 thread. Many refractors offer this thread, like:

♦ TS PHOTOLINE APO Refractors
♦ APM apos with 3" and 3.7" rack and pinion focusers
♦ Apos and EDs from Long Perng
♦ Larger apos from William from 102 mm aperture
♦ CFF apos

We offer adaptions for other apos and focusers, like adaptors to M63x1, Starlight 3" and 3.5" Feather Touch or M74 thread (Skywatcher ESPRIT).
 

Which refractors can be combined with the TSFLAT2,5:

In general, all refractors with focusers from 2.5" can be used. However, the TSFLAT2,5 needs a backfocus of at least 145 mm from the M68 connection. That is the distance of the connecting thread of the focuser to the focus. Almost all refractors offer this backfocus.
 

Connecting a camera to the TSFLAT2,5:

For best results, a correct distance to the camera sensor is necessary. This distance is measured from the female M69 thread of the corrector. The thread itself does not count.

♦ Focal length up to 500 mm ... 106 mm
♦ Focal length 510-600 mm ... 101 mm
♦ Focal length 610-700 mm ... 96 mm
♦ Focal length 710-800 mm ... 91 mm
♦ Focal length 810-950 mm ... 88 mm
♦ Focal length from 1000 mm ... 87 mm

If using filters, add 1 mm distance for compensating the glass path of the filter.

We offer different connection adapters for the TSFLAT2,5:

♦ TSVM6910 ... M69 extension with 10 mm length
♦ TSVM6930 ... M69 extension with 30 mm length
♦ M69-M48 .. Adaption to M48 with 36.5 mm length
♦ M69a-M68a ... Adaption to M68 with 5.3 mm length

With these connection adapters, you can adapt your camera according to your needs.

With the adapter set TSFLAT25A, we can accomplish the complete adaption for you: You get an optimized adapter package at a fixed price from us. From you, we only need the following specifications:

♦ Which connecting thread do you have at the telescope side?
♦ What is the distance from the connecting thread to the camera sensor? Off-axis guider, filter wheel ... is included.
♦ Which refractor do you use?
