DISCLAIMER: The larger the aperture, the more light a telescope will gather and the fainter the object you can see. Here is a range of magnitudes you might expect to see. Given excellent sky conditions and good optics, a well trained eye can sometimes add up to 0.8 magnitude to these values. Limiting Magnitude depends on much more than the instruments aperture. ... One formula is for aperture in inches the other is for aperture in millimeters. ... Aperture (inches) . ... 15.2 . ...
