The ZWO Seestar Tripod Head TH10 (with the TC20 tripod) is built for easier equatorial-style use with ZWO Seestar smart telescopes, with fluid damping for smoother movement. It is compact, supports a substantial payload, and offers wide pan and tilt range, but compatibility depends on your specific Seestar model and setup angles.
Ulanzi T100 is a compact CNC aluminum ball head built for quick camera swaps and flexible shooting angles. It combines a 1/4 to 3/8 adapter, 360° pan, 90° tilt, and an integrated cold shoe, plus an Uka quick-release plate that’s designed to speed up setup for vlogging, video, and travel photo work.
The Kado 1/4" screw thread to 17mm ball head adapter is a compact mounting connector that lets you attach a 17mm ball-head style bracket to 1/4" tripod hardware. It is best for small device mounts like phones, portable monitors, webcams, GPS units, and action cameras, with smooth 360-degree angle adjustment. The main caveat is fit: it only helps when your mount and device use the compatible thread and ball-head style.
