The Lumicon Easy Guider is one of the most powerful astrophotography accessories available today, with the largest guide camera field of view available.
This 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.
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.
Digital imagers may require an extension piece for use with SLR cameras.
