0.5x focal reduction - 1.25" - for observation & photography
The TS optics 0.5x reducer shortens the focal lengths of the telescope by 50% and doubles the optical speed and field of view. This advantage can be used visual and phototgraphical with cameras with smaller sensors.
The adaptation:
Just thread the reducer into the 1.25" filter receptacle of your foto adapter or eyepiece. The reducer has a suitable thread.
Photographical use:
This is the main use for the 0.5x reducer. It doubles the field of view and alters the photographic speed of your telescope accordingly. It can illuminate a field of approx. 12mm diameter.
Especially at cameras with smaller sensors up to ca. 13mm this effect is wanted when photographing bigger fields.
Examples:
ATIK ... cooled CCD cameras
Mintron ... sensitive video cameras
Webcam (e.g. Philips)
For visual use:
This is also possible. But nevertheless, in this realm the reducer is not as versatile as in photography.
It is only useful with 1.25" eyepieces with max. 25mm focal length; using bigger eyepieces will cause vignetting.
When the reducer is screwed into the eyepiece filter thread, the focal point moves approx. 5mm intrafocal.
Technical details:
-- Reducing factor: 0.5x (depending on the projection distance)
-- max. distance to the camera sensor: approx. 55mm
-- 1.25" filter thread (M 28.5 x 0.6) - on both sides
-- Optical system: multi-coated doublet
