SkyWatcher Sky-Watcher Evostar 150DX ED 0,77x fokusa attāluma reduktors

Focal reducer designed for use with the Sky-Watcher Evostar 150DX ED refractor .

It is used to reduce the focal length to0.77x, thereby improving field correction. At the same time, due to the shortened focal length, the telescope's aperture increases tof/6.2,which in turn66 %shortens exposure time and increases the field of view, which is extremely important in astrophotography. This three-element reducer guarantees a fully illuminated34 mmlight circle, suitable for APS-C sensors, it can also be used with full-frame lenses.

Using theSky-Watcher Canon EOS M48x0.75orSky-Watcher NIKON M48x0.75adapter, we can connect the camera to the reducer. With the included M48 adapter, the back focus is 55 mm, and when the adapter is removed, we expose the internal M71x1 thread with a maximum 75 mm back focus, intended for custom-made adapters.

The reducer hasFMCcoatings and a filter thread.

2.22 x 1.48degree field of view with a full-frame sensor.

1.45 x 0.97degree field of view with an APS-C sensor.

The reducer is only suitable for Evostar 150DX ED telescope focusers.
