The Hyperion eyepieces has both 1 1/4" and 2" barrel for fitting into
either size focuser or diagonal. Both barrel sizes have a safety groove
that offers a safe use in telescope. Each Hyperion features Baader's
Phantom group Multi coatings for maximum light transmission and the
ultimate in image contrast. The Hyperion eye pieces features two
photographic threads that is, M43 and SP54, that are located under the
rubber eye-cap or beneath the thread protecting ring, which is made of
high quality and aging resistant silicone rubber. The Baader eyepieces
offers Phantom Group Coating that is a 7-layer broadband coating with
extremely low residual reflection. All these different anti-reflection
coatings on each lens surface have then been optimized to be most
effective where the human eye has its highest sensitivity at night that
is, at about 520 nm in the green region of the visible spectrum. The
eyepieces can be combined with a Baader adaptor ring in order to mount a
camera directly onto the eyepiece. Baader offers a large number of
adapting rings and fittings to make the Hyperion suitable for all tasks
in astronomical and nature photography as a high quality projection
optic or as a tele-extender. |
