TS-Optics PHOTOLINE Full Frame APO Corrector / Flattener for astrophotography

High-end flattener for fast Apo refractor telescopes

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 at a glance

• 
  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

There are adaptions for other apos and focusers, like adapters 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.
