Omegon 0.5X reducer for photography

Omegon 0.5X reducer - reduces the focal length for visual and photographic use

This reducer halves the focal length of your telescope, giving you a much wider field of view. You can use this, for example, for doing astrophotography using an astronomy webcam.

Screw it in and you're ready to go

Using the reducer is ingeniously simple - it is threaded for attaching to a 1.25" filter thread, which lets you easily screw it into any 1.25" eyepiece or 1.25" camera adapter.

The simple way to increase your webcam's field of view

Screw the Omegon reducer into the filter thread on your camera and so double the size of the photographic image field. This lets you 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 obtain even larger image fields with your astronomy webcam if you attach an extension tube (e.g. 25mm) between the reducer and camera.

The advantages in a nutshell:

• 0.5X reducer for screwing into the filter thread
• expands 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
