Off-Axis Guider 12.5x12.5mm Prism Astronomical Telescope Accessories OAG Offset Guide for Astrophotography
Product Description
Product Bief:
* Designed for deep-sky imaging with Schmidt-Cassegrain and refractor telescopes, this Deluxe Off-Axis Guider lets you image and guide simultaneously through a single telescope. This also eliminates tracking problems such as differential flexure and mirror shift that commonly occur when using a separate guide scope. The imaging camera sees the same movement the autoguider sees, resulting in highly accurate tracking for pinpoint stars. Prism tilt adjustment with captive thumbscrew and more than 100 degrees of radial movement allow for easy guide star acquisition. Coarse and helical fine focus adjustments make focusing easy and accurate. The Deluxe Off-Axis Guider can be used with most imaging cameras, including DSLRs, and telescopes with sufficient inward focus travel.
* Deluxe Off-Axis Guider (OAG) allows simultaneous imaging and guiding through the same telescope.
* Auto guider cameras with either T-threads or a 1.25" nosepiece can be used.
* Incorporates a prism tilt adjustment and over 100 degrees of radial adjustment to simplify guide star location and centering.
* A separate guide scope - that can introduce flexure and other guiding inaccuracies.
* A small adjustable prism protrudes into a part of the primary telescope's light path and directs the image of a suitable guide star in the field of view up into the eyepiece.
Package Include:
1 x Off-Axis Guider
