TS Optics PHOTOLINE 2" 1.0x Flattener for Refractors and Apos
With the TSFLAT2, a professional field corrector for apochromats, EDs and normal Fraunhofer achromats is available to the astrophotographer. The corrector is suitable for refractors from f/4 to f/9.
Advantages over other 2" correctors
-
Clear aperture of 45 mm without vignetting, even full-frame size sensors can be used.
-
Generous working distance between 108 mm and 128 mm, depending on the focal length of the telescope.
-
M48x0.75 - 2" filter thread at the telescope side for filters and at the camera side for further adaptions.
-
Also visually usable, the sharpness in the field is significantly improved.
-
Easy adaption vie 2" barrel - with the adapter package TSO-TSFLAT2A you get a complete adaptation from the flattener to the camera from Teleskop-Service.
-
Suitable for all 2" focusers, the corrector is completely sunken into the focuser
- Inner blackening and anti-reflex thread
Recommended distances from the M48x0.75 thread to the corrector
In principle this rule applies: the shorter the refractor´s focal length, the longer the working distance to the sensor has to be.
-
focal length < 450 mm: 128 mm
-
focal length 450-490 mm: 123 mm
-
focal length 500-550 mm: 118 mm
-
focal length 560-590 mm: 116 mm
-
focal length 600-690 mm: 113 mm
-
focal length 700-800 mm: 111 mm
-
focal length ab 800 mm: 108 mm
An underrun or an overrun of the distance of up to 5% has no visible effect on the sharpness in the field of sensors with formats up to APS-C. With larger sensors, the tolerance is reduced to 1-2%.
