Lumicon 1.25 Inch Easy Guider - Newtonian/Refractor


Lumicon 1.25 Inch Easy Guider - Newtonian/Refractor is one of the most powerful astrophotography accessories available, incorporating a unique, patented radial adjustment for finding bright, off-axis guide-stars.

This 1.25″ low-profile Easy Guider features a large pick-off prism, making bright guide-star selection a breeze. It uses telescope optics directly for pinpoint guiding accuracy. This method is superior to using guide-scopes, which can flex with respect to the main telescope.

The compact design of the Lumicon Newtonian/Refractor Easy Guider allows for installation in seconds and requires 0.5″ of back-focus.

Compatible with Newtonian and Refractor telescopes with 1.25" eyepiece holder.

Note: Digital imagers may require an extension piece for use with SLR cameras. The following accessories are required for photography: A guiding (reticle) eyepiece (or auto-guider) and a camera-specific T-ring.

Benefits of Off-Axis Guiding

    • Guiding occurs with the same light path as the imaging detector thereby eliminating the effects due to differential flexure/slop of the auxiliary guide scope.
    • Differential flexure in guiding setups often introduces errors far worse than the actual corrections actually needed. Off-axis Guiding avoids this problem.
    • Auxiliary guide scopes are blind to image shifting due to primary mirror "flop" in telescopes with moving primary mirrors (SCT's). Off-axis guiding corrects for this problem
    • Guiding occurs at the same focal length as the main imaging camera. Although CCD guiding software can compute tracking errors to sub-pixel accuracy, many guide scope combinations have marginal or too-short focal lengths to be properly effective. Off-Axis Guiding avoids this problem.
