    More About the Orion Deluxe Mini 50 mm Guide Scope

    Orion's favorably compact Deluxe Mini 50 mm Guide Scope contains a helical fine-focus mechanism for quicker, more accurate focusing of potential guide stars.

    The deluxe edition of the popular Orion Mini 50 mm Guide Scope is made to be used with the separately sold Orion StarShoot AutoGuider or similar CCD autoguider device with a small chip. The Orion Mini 50 mm Guide Scope is perfect for guiding up to 1500 mm focal length imaging telescopes for long-exposure astrophotography. Features a machined and anodized helical focuser with a fixed-orientation design that will keep from rotating the installed StarShoot AutoGuider or similar device when focus adjustments are being made. The helical focuser only advances the attached autoguider in or out while retaining its established orientation. Astrophotographers are sure to welcome this as it guarantees that focus adjusting will not affect the field of possible guide stars.

    The included helical focuser is machined and anodized. It has a 12.5 mm travel range, and a tight thread tolerance to ensure absolutely no backlack and eradicate flexure-causing "play." The helical focuser ring is ribbed to provide a comfortable grip for adjustments, while a convenient thumbscrew lock helps the focuser maintain its position once ideal focus has been obtained.

    The Orion Deluxe Mini 50 mm Guide Scope with Helical Focuser gives any astrophotographer access to precisely focused autoguiding at an affordable cost, while elevating the guide scope to a position that had been occupied by a telescope finder. Due to the high level of guiding accuracy provided by newer autoguider devices like the Orion StarShoot AutoGuider, modern astrophotographers can use much shorter focal length guide scopes with smaller apertures instead of the large, cumbersome models used previously. Utilizing an optically faster guide scope such as the Deluxe Mini 50 mm Guide Scope can save astrophotographers valuable time, space, and money, while still supplying unparalleled accuracy to long-exposure astro-images that only autoguiding can achieve.

    This achromatic refractor guide scope with helical focuser has and aperture of 50 mm with 162 mm focal length (f/3.2) and comes with an adjustable dovetail guide scope bracket, dovetail mounting base, and an adapter plate. Orion's Deluxe Mini 50 mm Guide Scope allows astro-imagers to easily enjoy autoguiding precision in their astrophotos. All this conveniently compact device needs is a separately sold StarShoot AutoGuider or similar CCD autoguider with small chip and it's ready to go! Included guide scope bracket fits into the standard Orion dovetail finderscope base available on most Orion telescopes. In case your telescope doesn't have a dovetail base or has one currently occupied by a frequently used finder, the included dovetail base and attachment hardware permits the Deluxe Mini 50 mm Guide Scope to be connected to any optical tube. The included adapter plate can also be used to connect the dovetail base and Guide Scope to any standard dovetail plate, or side-by-side plate if desired. At only 1.2 lbs. (19.2 oz.), the Orion Deluxe Mini 50 mm Guide Scope with Helical Focuser is extremely lightweight.

    While it's not being employed for autoguiding, this Guide Scope can instead be used as a finderscope. Simply insert an optional Illuminated Centering Eyepiece (sold separately) into the helical focuser and the versatile Deluxe Mini 50 mm Guide Scope now serves as an 8x50 illuminated finder!
