 Big Prism Off-Axis Guider with Extra Extension Tubes

Off-Axis Guider is an essential astroimaging accessory for long focal length telescopes that require the most accurate guiding possible. This high quality Off-Axis Guider uses a prism to intercept a small portion of the telescopes focal plane (outside the field of view of the main imaging camera) to locate a guide star. Any movement seen by the guide star will be the exact same movement seen by the imaging camera. Guiding this way will correct for tracking errors, as well as opto-mechanical errors or flexure. The result: better astro-images with pinpoint round stars.Providing a large 12.5mm x 12.5mm prism that can be adjusted to move closer to the center of the telescopes focal plane, depending on the size of the imaging camera. This results in brighter guide stars, with the help of the large prism to fully illuminate the autoguider sensor. Off-axis camera guide-port can be focused independently (0-15mm range) 10mm optical path Off-axis camera guide-port can be focused independently (0-15mm range) 3-position, 120 degree rotatable design (imaging camera side) Included two free adapters: Telescope adapter 48mm(M) to 2″ nosepiece, threaded for filters and a T-extension(M42 x0.75) for T/T2 adaptor for camera side.With Four M42x0.75 Extension Tubes (threaded on both sides) to give you whatever combination you may need.Without the extension tubes and the telescope adaptor, it will be a so called ‘Thin off-Aixs Guider’.
