The primary and secondary mirrors are all made of enhanced aluminum coating, and the reflectivity is guaranteed to be above 95%. The secondary mirror has a new lever adjustment function that can be moved in a horizontal position. The 3-inch dedicated focuser ensures smooth operation without slipping when astrophototgraphy with accessories.
All CNC aluminum parts and novel hollow handles can be connected to different accessories, and the appearance and mechanical quality are of high standards design to meet the wants and needs of today’s demanding astronomer.
The optical path includes a triplet 3" field flattener, combining the system ensures full-frame photography and vignetting control. The two M54×0.75 threads and M48×0.75 threads at the rear of the focuser can meet different needs, are convenient to connect to most commercially available imaging-terminal and achieve perfect focus.
