Description
TS Reducer 0.5x - 1.250.5x 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.
Reducer with Mintron cameraPhotographical 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)
TS reducer w/ standard box
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.
