EYEPIECE OPTIONS
A wide range of eyepieces are available
for use with Classic Fieldscopes.
Choosing the best eyepiece is often
confusing but making the right choice
will depend on price and application.
It is important to remember that the
eyepiece is an integral part of the
whole set-up and opting for a lower
quality lens will make a difference
to the overall image quality derived
from the fieldscope.
HDF Eyepieces [Except 40862 HDF zoom
eyepiece]
The preferred choice for quality and
viewing comfort, HDF eyepieces have
large dia. eyelenses and provide 'walk-in'
field of vision. All eyepieces feature
long eyerelief for full field of view
with or without spectacles and fixed
magnification models are wide angle.
HR Eyepieces
Good choice as either supplementary
eyepiece in combination with HDF or
single eyepiece for the value conscious.
Eyepieces 40812, 40813WA offer full
field of view with spectacles but
high power models including 40821
zoom do not.
Classic Eyepieces
The original eyepieces for the Classic
providing an inexpensive viewing option.
OR Eyepieces
Short focal length [high magnification
lenses] used for astronomical observation.
