New Orion 8891 Mini 50mm Guide Scope Astrophotography

*This listing is for a brand new item in its original, open box.
*All pictures are of the actual item you will receive, and only what is pictured
is included in this sale.


  • Compact mini guide scope designed for use with astrophotography
    telescopes up to 1500mm focal length
  • Mini 50mm guide scope with bright, wide-field optics puts numerous
    potential guide stars in view so you'll never have to search for one!
  • Adjustable-aim dovetail guide scope bracket installs on virtually any
    astrophotography telescope quickly and easily
  • Very small and compact autoguiding system adds hardly any weight to an
    astrophotography setup and can conveniently be stashed in an accessory case
    between uses
  • Designed for use with Orion StarShoot AutoGuider (sold separately) and
    other similar small-chip CCD autoguiders


The Orion-designed Mini 50mm Guide Scope is a complete and compact guide
scope solution designed for use with the Orion StarShoot AutoGuider (sold
separately) or similar small-chip CCD autoguider devices. The Orion Mini 50mm
Guide Scope is ideal for guiding long-exposure astrophotographs with imaging
telescopes up to 1500mm in focal length.

Thanks to the high level of guiding accuracy offered by modern autoguider
devices such as the Orion StarShoot AutoGuider, astro-imagers of today can use
guide scopes with much shorter focal lengths and smaller apertures compared to
the large, bulky models used in the past. Using a more optically "fast"
refractor as a guide scope can save astro-imagers time, space, and money, but
will still provide the unrivaled accuracy that only autoguiding can bring to
long-exposure astrophotographs. Although modern dedicated autoguider devices
allow small, optically fast guide scopes to be used with excellent results,
there is an unfortunate scarcity of quality offerings available. That is, until
now. The Orion Mini 50mm Guide Scope brings autoguiding into the realm of
affordability for any astrophotographer, and brings the guide scope to a
position that was previously occupied by a telescope finder scope.

Consisting of a 50mm aperture, 162mm focal length (f/3.2) achromatic
refractor guide scope, an adjustable dovetail guide scope bracket, an 1.25"
aluminum parfocal ring, a dovetail mounting base, and an adapter plate, the
Orion Mini 50mm Guide Scope makes it easy for any astro-imager to enjoy the
precision of autoguiding in their images. All this pint-sized setup requires is
a StarShoot AutoGuider (sold separately) or similar small-chip CCD autoguider
and it?s ready for night, camera, action! The guide scope bracket fits into the
standard Orion dovetail finder scope base found on most Orion telescopes. If
your imaging scope doesn?t feature a dovetail base or has one already occupied
by an oft-used finder, the included dovetail base and attachment hardware lets
you attach the Mini 50mm Guide Scope to any optical tube. Alternatively, the
included adapter plate can be used to attach the dovetail base and Mini 50mm
Guide Scope to any standard dovetail plate or side-by-side plate if preferred.

The featherweight guide scope tips the scales at a mere 16oz., and has been
designed for use with imaging telescopes measuring up to 1500mm in focal length.
This one-pound wonder Mini 50mm Guide Scope features fully multi-coated optics
and a focus-adjusting front ring with locking collar. The included parfocal ring
makes it easy to repeat autoguiding performance night to night, by letting you
set the ideal focus position of the autoguider.
