-Vignetting, edge field aberrations and pupil movement - all introduced when using Barlows with long focal length eyepieces, are minimized.
-Telecentric operation (field rays leave parallel to optical axis, unlike Barlow lenses which diverge rays). -This is ideal for Hydrogen-alpha filter use such as with Daystar models.
-High performance for image amplification, CCD or film (some of the finest Earth-based planetary imaging is being done with Powermates).
