Precise Positioning Guaranteed: Objects centered in the eyepiece automatically align perfectly on the camera sensor; Effortlessly capture planets and deep-sky targets without guesswork or test exposures
Simplified Focusing Process: Switch between eyepiece and camera instantly using the flip mirror; Achieve critical focus visually through the eyepiece; ensuring sharp results for both imaging and observation
Parfocal Helical Focuser: The adjustable helical focuser synchronizes eyepiece and camera focal points; Maintain consistent sharpness when flipping between viewing and imaging modes
The extension tube has a M48x0.75 interior thread and a M48x0.75 exterior thread for elegantly solving spacing problems in astrophotography
The required spacing can be achieved by combining several extenders of differing lengths; you can use 1 piece; 2 pieces; 3 pieces or 4 pieces of the extension rings as you like
