مجموعة OAG فائقة النحافة مع أنبوب تمديد الموجه التلقائي

Was really worried about back focus clearance on my rig, but the integrated autoguider extension tube solved that issue perfectly. Machining is clean and everything threaded together without any wobble.

Swapping out my old guiders for this slim OAG freed up a ton of back focus on my imaging train. The prism is tiny but grabs plenty of stars for PHD2, and the extension tube threads on smooth with zero tilt.

Finally got this OAG dialed in last night—the autoguider extension tube made hooking up my guide camera a breeze, and the slim profile cleared my filter wheel without any issues.
