Meet the GODO Telescopes: 16” Meade ACF Catadioptric Reflector

Written in collaboration with Claire Gibson, Lowell Educator

Each of the Giovale Open Deck Observatory (GODO)’s six state-of-the-art telescopes were hand-selected to provide a breathtaking stargazing experience that is unrivaled by any other public observatory in the continental United States. In this blog series, we’ll be taking a deep dive into what makes each of the GODO telescopes the best of their kind.


Meet the GODO Telescopes: 16” Meade ACF Catadioptric Reflector

This 16″ Meade telescope is a catadioptric reflector, meaning that it combines both lenses and mirrors to create a focal length of over 13ft, though the telescope itself is much smaller. Its optical path uses two mirrors and a corrector lens to fold the light inside the telescope. This particular design corrects errors at the edge of the field of view, so that every star looks sharp.

The Meade’s hybrid nature allows a narrow-field view which is suited to smaller objects like planetary nebulae, smaller star clusters and double stars, and it can show great detail on planets like Jupiter and Saturn. When looking straight through the opening of the telescope, you can see the blue tinted 16” front glass plate. This is the Schmidt Corrector Plate, which adds aberration corrections to the Cassegrain optical design, referring to the idea that this telescope uses both lenses and mirrors. Overall, the Meade telescope does well with just about anything in the night sky, from bright planets to the Ring Nebula. 

The telescope is mounted on an articulating pier, which allows the height to be easily and quickly adjusted to allow comfortable viewing for all guests.
