HamGeek EAF Automatic Star Focuser Pro + Dedicated Handle + Temperature Controller + 42mm Focuser with Round/ Convex Adapter Ring for Astronomy
EAF Description:
- Supports for Ascom and indi protocols.
- 5V power supply, only requires USB interface data cable to connect to the computer, wiring and power supply is simple.
- Supports for Ascom and Indi. Automatic focusing can be achieved in NINA, MDL, Sharpcap, or kstars. If the aforementioned astronomical software is not required, there are also specially developed control software that can easily control the focusing device through a computer.
- Specially customized 35 high torque stepper motor, which is more segmented than EAF's motor, with 3840 steps per turn, high segmentation, and more steps in the focusing area.
About air travel (also known as backlash):
- Air travel is mainly generated by the mechanical structure of the focusing seat, and the air travel brought in by the focusing device itself can be ignored. Air travel exists as long as it is a mechanical device, and it only needs to be offset in the software, which does not represent the performance of the focusing device.
42mm 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.
