Description

Screw it on and you're ready to go.

Using the reducer is ingeniously simple: it's threaded to fit a 1.25" filter thread, allowing you to easily screw it onto any 1.25" eyepiece or 1.25" camera adapter.

The easy way to increase the field of view of your webcam

Screw the Omegon Reducer onto your camera's filter thread and double the size of the photographic image field. This allows you to take images of much larger areas of the lunar surface, for example. The reducer is also great for taking videos of the Moon using your webcam. You can get even larger image fields with your astronomy webcam if you connect an extension tube (eg 25mm) between the reducer and the camera.

The advantages in a nutshell:

0.5X reducer to screw on the filter thread

expand the image field of your webcam

more light intensity

can be used visually with an eyepiece

also optimal for video astronomy

take images of larger areas of the Moon's surface

Technical specifications:

mounting threads - 1.25" filter thread (28.5x0.75 M) on both sides

free light transmission - 22.5mm lens aperture

2 lenses for better correction - cemented together and coated

85mm focal length

Expert comment:

The reducer is useful for chips from 0.25 to 0.5 inches (webcams, DMK, Watec) and focal ratios of f8 (refractors, Maksutov and SC). You need about 5 cm of back focus. The result is an optical system from f4 to f6. The reducing effect can be varied using the distance from the chip, e.g. by filter rings.

The reducer is not suitable for DSLRs and large CCD cameras as the chips are not fully illuminated.
