Optec Sagitta OAG 3'' Manual Off-Axis Guider (19342)

Optec Sagitta OAG 3'' Manual Off-Axis Guider

Optec engineers designed the Sagitta OAG to provide a solution for remote imagers who require the ability to adjust guide camera focus independently of the imaging camera focus.

Robust New Off-Axis Guider for Large Cameras

Featuring a full 3-inch (76.2mm) clear aperture, the Optec Sagitta OAG 3” Manual Off-Axis Guider includes a high-quality fully multi-coated pick-off prism with 12.5mm clear aperture to the guide camera. Sagitta features a large brass split-clamp for attachment of any 1-1/4” format guide camera with plenty of range for setting the guide camera parfocal to the imaging camera. Adjusting the prism stalk height can be accomplished with a single tool and provides prism engagement adjustment of 12mm. Overall, guide camera adjustments exceed 42mm while the OAG body thickness is held at only 31.75mm or 1-1/4”.

Designed as a robust alternative for the OAG market, Sagitta can be installed and configured for years of unattended use. A new, shorter 3-inch dovetail standard, the OPTEC-3000-S, rounds out the package with a variety of mating adapters. Any required adapter not available from Optec’s expanding inventory can be ordered through Precise Parts (www.preciseparts.com) to complete the camera side or telescope side connections to your imaging gear.
