Extended Endurance with Argon-Purging!
The Explore Scientific 68° eyepieces are designed to be parfocal, meaning
they share a common focus point regardless of the focal length. This feature
makes it incredibly convenient to switch between eyepieces of different
focal lengths during your observation session, as only minimal focus
adjustments will be needed. This ensures you spend more time observing and
less time refocusing. It also makes this Explore Scientific eyepiece an
excellent choice for both beginner and experienced astronomers seeking an
efficient observing experience!
Extended Endurance with Argon-Purging!
While many eyepieces are nitrogen-purged to block moisture, dust, and mold,
Explore Scientific enhances durability by argon-purging these 9 mm
eyepieces. The larger argon atoms form a stronger, more secure seal. Argon
atoms are larger than nitrogen atoms and, therefore, they are less likely to
leak or diffuse their way through the seals over the life of the eyepiece.
Additionally, argon cools more slowly. Being argon-purged buffers the
effects of rapid temperature changes in the optics. Argon also has superior
inertness when compared to nitrogen (i.e., forming few or no chemical
compounds with other elements), which prevents adverse reactions with
eyepiece components and extends the longevity of the internal components. It
also prevents chemical reactions with other elemental contaminants that may
be introduced through a weakened seal. By making the eyepiece body
argon-purged, this waterproof eyepiece's internal elements will remain as
pristine as the day they were assembled!
Well-Rounded Features!
The Explore Scientific 9 mm star feature is the huge 100° AFOV, which gives
the observer a panoramic visual experience while relaxing the eye so subtle
details can be observed. With an apparent field of view that is maximum for
a hyper-wide eyepiece design, making it easier to locate objects! The
Ultra-Wide view helps non-motorized telescopes keep the target in view
longer without needing to reposition the base as often. This eyepiece comes
with a rubber eye cup that adds even more protection from stray light,
further enhancing contrast!
