Does A Focal Reducer Reduce Magnification at Alannah Bladen blog

Does A Focal Reducer Reduce Magnification. Because of this, a popular accessory for astrophotography is the focal reducer. Focal reducers reduce the focal length of the telescope, make the focal ratio faster, and the field of view wider. A reducer provides a magnification of less than 1. Focal reducers are essentially like a barlow with a magnification factor of less then 1. A focal reducer takes the light cone from a slower optical system, f/10 for example, and focuses it to a smaller area, effectively reducing the focal length and speeding up the focal ratio. They also generally correct for the aberrations in a particular type of scope. A barlow in effect multiplies the focal length of your telescope which increases. A wider field of view and a lower magnification is also useful, with some focal reducers and with some eyepieces, for visual. A barlow and a focal reducer do opposite things. It also increases the effective aperture as a result, and can be thought of as. An sct focal reducer with generally flatten a curved focal plane and maybe even reduce the coma. However, when you do use them, you can expect a reduction in the effective focal length of the lens, and unlike a teleconverter, you get the benefit of a wider maximum aperture.
