This was bought to provide a wide angle view on a telescope of 1000mm focal length without giving the very large exit pupil that would have resulted from using a longer focus 1.25" eyepiece to get a similar field. There is pincushion distortion, but I don't find this to be a great problem for visual use, and some chromatic aberration in the outer parts of the field on contrasty edges. However, the centre of the image has no obvious faults, and at only £64, I think the performance is quite acceptable.
