The appearance of Z4 breaks through the previous style of Sharpstar with its matte gray coating. Light gray lens tube plus dark gray focuser and tube ring, make the astrograph looks calm but vibrant. The tube ring has a handle on the top which is easy to carry and assemble. The handle is designed as a slot on which you can mount a finder base, etc.
Z4 uses a large 3.4” focuser with a 1:10 fine adjustment knob and a 360° rotator for easy focusing and angle adjustment. It has M86, M68, M54, M48 adapters, and the M48 one has an internal thread that can fit 2” filters. And a 300mm Vixen-style dovetail plate, makes it easier to balance on the equatorial mount.
