Product Description & Reviews
This small Guidingscope handles all the tasks of a "classic" Leitfernrohrs - but it is lighter and much easier to use! Previously used to long and large Leitfernrohre to find a guiding star. Eliminate the need to! The sensitivity of modern astro imagers is on your side. The Mini-Guidesope set as a viewfinder on your telescope.The 50mm Guide Scope is a complete and compact guide scope solution designed for use with nearly each autoguider and CCD camera in the market. The Guide Scope is ideal for guiding long-exposure astrophotographs with imaging telescopes up to 1500mm in focal length. Consisting of a 50mm aperture, 190mm focal length 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 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 or similar small-chip CCD autoguider and it's ready for night, camera, action! The guide scope bracket fits into the standard dovetail finder scope base found on most telescopes. If your imaging scope doesn't feature a dovetail base or has one already occupied by an oft-used finder, the dovetail base（not include）and attachment hardware lets you attach the 50mm Guide Scope to any optical tube. Alternatively, the included adapter plate can be used to attach the dovetail base and 50mm Guide Scope to any standard dovetail plate or side-by-side plate if preferred.
