CYCK 42mm Travel Telescope Focuser with Convex Adapter Ring + EAF Electronic Automatic Focuser for Deep Space Photography

CYCK 42mm Travel Telescope Focuser with Convex Adapter Ring + EAF Electronic Automatic Focuser for Deep Space Photography

Telescope Focuser Features:
- Almost no light leakage: provide a great guarantee for deep space photography.
- High interface precision: with standard new concept locking ring, there is no need to worry about coaxiality, untight locking or warping after locking.
- Quick-release two-speed components: You can quickly disassemble and assemble the two-speed components without disassembling the entire focuser to adjust the desired feel.
- Super large hand-wheels: the diameter of the coarse adjustment wheel reaches 38mm/1.5", and the diameter of the fine adjustment wheel is 28mm/1.1", which reduces the slippery feeling of hand twisting.
- 360-degree rotation: convenient for photographic composition and visual inspection [try to fix the angle so as not to affect the focal plane and balance of the optical axis, especially after adding electronic focuser.

Telescope Focuser Specification:
- Focusing range: 42mm
- Net weight: 710g
- Minimum height: 62mm

Adapter Ring Compatibility:
- The round adapter ring version is suitable for Sky-Watcher 130PDS/250F4 telescopes with round focusing base.
- The convex adapter ring version is suitable for Sky-Watcher 150 and above diameter telescopes and all series of Newtonian reflecting telescope DOB with convex focusing base.

EAF Description:
- Introducing 5V EAF, this electronic focuser, like its previous version, enables precise, dynamic focus control for planetary and deep-sky imaging, while only connected to a 5V USB-port.
- Compared to the old version of the EAF focuser, the main change of the 5V EAF is to eliminate the need for a 12V power supply port. Now you can directly connect it to your camera, laptop or ASIAIR PRO via the USB 2.0 port and use a cable for both data transmission and power supply! This makes the cable management much easier, as well as reducing the need for additional power outlets.
- The innovative decorative pattern on the EAF is inspired by the changes of Airy disk during focusing showing how the focusing curve gives a local minimum at best focus – giving an easy explanation on how the EAF works just with a glance on the cover!
