XY-241009 CA3 Fine Tuning Astronomy Guidescope 3 Way T-mount M42 for 1.25-Inch Telescopes/CCDs

Features:
- For 1.25-inch guiding CCD: CCD can achieve synchronous focusing with guiding illumination eyepiece, that is, after focusing the eyepiece, adjust the reflector, and the CCD can also adjust the rear synchronous focusing.
- The reflectivity of the visual light port has been reduced to about 70%, which basically achieves the visual detection of star magnitude = the same magnitude that can be shot on CCD, and is suitable for guiding stars.
- Suggested use of eyepiece: PL10-25, some special eyepieces may not achieve synchronized focusing between the eyepiece and CCD.
- Suitable for guidescopes with a zenith angle of over 60MMN (note: double helix focusing guidescopes are not suitable for use) Testing method: if the guidescope equipped with a 1.25-inch zenith support focusing, this guiding port can be used.
