The SV238 OAG can be used with the SV226(M54) model, and the upgraded SV226P(M42) model.
SV238 Off-Axis Guider
The OAG is an essential astroimaging accessory for long focal length telescopes that require the most accurate guiding possible. The SV238 OAG uses a prism to intercept a small portion of the telescope’s 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 astroimages with pinpoint round stars.
Large 8×14mm prism
SVBONY SV238 OAG off-axis guidescope captures more starlight and provides a wider field of view. It can easily find the right guide star even in sparse star fields, ensuring a higher guiding success rate and stable performance.
Adjustable Prism Height
This OAG features precise prism height adjustment for flexible alignment with various cameras and telescopes. Fine-tune the prism position to capture bright guide stars and avoid ghosting in the primary camera, ensuring clear, stable images under any conditions.
Dual Helical Focuser
A dual helical focuser on the OAG allows ultra-fine, backlash-free focusing of the guide camera, ensuring pinpoint guide stars and accurate long-exposure tracking.
CNC-Machined Unibody
It withstands outdoor temperature shifts without deformation, delivering stable performance for astrophotography in all conditions.
Wide Thread Support
M54, M48 & M42 adapters let you connect effortlessly to the majority of cameras and telescopes without extra adapters. All-in-One Accessory Kit — Comes with multiple adapters and tools, ready for diverse astrophotography applications.
