Meade Super Plössl and Super Wide Angle Eyepieces are
ideal for general-purpose astronomical or terrestrial observing.
The typical Starfinder Dobsonian user may wish to add 2 or 3
of these eyepieces to his or her telescope. An introductory
selection might include the SP9.7mm and SP15mm. The more
advanced observer will perhaps select the SP 9.7mm, SP
12.4mm, and SWA 18mm. The Super Wide Angle Eyepiece
series yields extremely wide fields of view, perfect for the
examination of star fields, diffuse nebulae, or for terrestrial
applications. Under very steady seeing conditions Meade UWA
4.7mm and 6.7mm eyepieces present the widest fields of view
obtainable at high powers and are excellent eyepieces for the
Moon and planets.
Filters: Thirteen color filters are
available for significantly increased
contrast and resolution of detail on
the Moon and planets. For
example, the #80A (blue) filter
effectively enhances the reddish-
colored detail on the surface of
Jupiter. These filters thread into the barrels of all standard 1.25"
O.D. eyepieces and may also be used for eyepiece projection
photography.
Illuminated Reticle Eyepiece: P e r m i t s
easy visibility of guiding crosslines even
against the darkest skies. The standard
#702A double-crossline, phosphorescent-
enhanced reticle allows for variable
illumination from faint to very bright.
Magellan I: The Magellan I accessory will
permit you to add a powerful pointing tool
to your Starfinder Dobsonian telescope.
Encoders supplied with this product for the
R.A. and Dec. axis can be easily installed
in factory machined mounting features.
Once installed, the Magellan I will allow the
electronic selection and pointing of the
telescope at a large number of catalogued
objects in the sky.
#140 2x Barlow Lens: The Barlow
Lens, or Telenegative Amplifier, is a
convenient accessory used to
increase the effective magnification
of any given eyepiece. The Barlow
Lens is inserted into the focuser and
accepts all standard 1.25" O.D. eyepieces.
Viewfinders: In addition to the standard-equipment 5x24mm
viewfinder supplied with all Starfinder telescopes, the higher
power/larger aperture 6x30 and 8x50mm viewfinder are
available to substitute or retrofit.
