1.5 mm in daytime), you may see the shadow of the secondary mirror as a dark spot, 
and the distance of the eyepiece to the reducer must be maintained for it to work as 
desired. Therefore, a long focal length eyepiece is easier to handle for visual use than 
a reducer.

Typical long focal length eyepieces give you:

EP = Exit pupil | FoV = Field of View

The field stop of the Hyperion 36 in 1¼" configuration is 32 mm, providing the largest 

field of view achievable with 1¼". The field stop of a typical long focal length 1¼" eye-
piece is a maximum of about 26 mm, that of a 2" eyepiece about 45 mm. 

The achievable field of view is determined both by the diameter of the field stop of 

the eyepiece and that of the H-alpha filter; a longer eyepiece focal length or a 2" nose-
piece therefore do not necessarily also provide more field of view.
