The TS optics 0.5x reducer shortens the focal lengths of the telescope by 50% and doubles the lens speed and field of view. This advantage can be used visual and phototgraphical with cameras with smaller sensors.

Due to the doubled lens speed, the exposue time is reduced even to a quarter!

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. 12 mm diameter.

Especially at cameras with smaller sensors up to ca. 13 mm this effect is wanted when photographing bigger fields.

Examples:

ATIK - cooled CCD cameras
Mintron - sensitive video cameras
Webcams (especially 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. 25 mm focal length; using bigger eyepieces will cause vignetting.

When the reducer is screwed into the eyepiece filter thread, the focal point moves approx. 5 mm intrafocal.

Useful additional equipment:

The TSVF1 rises the distance between reducer and chip and increases the reduction factor from 0.5 to 0.3x, but is recommended only for photography.
Reducing factor:0.5x (depending on the projection distance)
Max. distance to the camera sensor:approx. 55 mm
Connection:1.25" filter thread (M 28.5 x 0.6) on both sides
Height of the cell:10.5 mm (without thread)
Optical system:multi-coated doublet
Free aperture:22.5 mm
Reducer with filter threads

"Kleines Teil mit großer Wirkung, zumindest für das Beobachten. Fotografisch habe ich es noch nicht testen können."

"Ich benutze den Reducer bei der Planetenbetrachtung, er erhöht den Kontrast und die Helligkeit. Bei der Mondbetrachtung könnte er aber die Abbildungsgröße noch etwas mehr verkleinern. Ich verwende u.a. ein Celestron NexStar 8se mit 25mm Super Plössl Okular,TS-Mondfilter und dem TS-Reducer. Die Verarbeitung der Filter ist sehr gut."

"Ich habe es versuchsweise für die Okulare im Baader Mark V Binoansatz mit GWK 2"" 1,7x ausprobiert, um die Vergrösserung zu reduzieren und somit ein grösseres Gesichtsfeld zu kriegen. Die Vignettierung war jedoch extrem und brachte keinen Gewinn am Gesichtsfeld."

"Die Brennweitenreduzierung erlaubzt es mit dem C8 ein ganzes Bild der Sonne aufzunehmen. Es hat sich bis jetzt im Einsatz bewährt und es gibt keine merklichen Einschränkungen."
