'Alopeke & Zorro Field of View

You are here

'Alopeke and Zorro have two sets of optics which allow selecting between "Speckle" mode and "Wide-Field" mode. Both modes slightly underfill the detector resulting in circular fields-of-view.

The diameter of the vignetted 'Alopeke wide-field is ~60", however, the diameter of the unvignetted 'Alopeke wide-field is ~35".
