ASI T2-Tilter - Tilt flange Adjustment of image plane and sensor position Many astrophotographers know the problem: You focus as good as possible and in 1-2 corners the sharpness is still not satisfying. The result is a bad compromise, by changing the sharpness setting until the stars appear relatively evenly "sharp" or by simply cutting away the corner. Some possible causes of this problem: ♦ a slight tilt of the camera sensor (only a few fractions of a millimeter are enough) ♦ a tilt of the focuser ♦ a slight tilt of the field plane of the telescope (very common with Newtonian telescopes) ♦ a tilting of the eyepiece-side accessories during clamping This is the solution: With the ASI T2 tilter you simply adjust the chip of the camera to the field of the telescope, no matter where the cause of the tilt comes from. You only have to keep the orientation of the whole adapters, correctors and camera. Connecting the camera to the tilter: In principle, any suitable camera can be connected to the tilter via the T2 thread. However, additional bores also allow the connection directly to the camera body on the following ZWO cameras: ♦ ASI294/ASI1600/ASI183/ASI533 Pro cooled ♦ ASI294/ASI1600/ASI183/ASI174 uncooled With the ASI071 and ASI 2600 Pro the housing is differently dimensioned, the direct connection does not work. There it only works via the T2 thread.
