In order to decrease heating inside the telescope and reduce chromatic aberration, an aperture stop can be used.
It features a front aperture stop, a hyperbolic primary, a flat secondary mirror, and a two-element Ross-type corrector.
Maybe the aperture stop is masking optical errors in a flawed objective, or maybe it's just allowing a mediocre eyepiece to perform better by increasing the telescope's f/ratio.
