Specifications:

Name: 2-inch Dual Speed Toothed Focusing Seat

Please bring your own disassembly tools: a set of Allen wrenches is required

Round mouth adapter ring version is suitable for telescopes with Xinda 130PDS and 250F4 focusing bases that are fully circular

Convex mouth adapter ring version is suitable for telescopes with Xinda 150 and above aperture, all Bull Anti DOBs, and focusing bases with convex mouths

Features:

1: Almost no light leakage: providing the greatest guarantee for deep space photography

2: High interface precision: equipped with a new concept locking ring as standard, no longer worrying about coaxiality, locking failure, or curled edges after locking

3: Adopting a quick detachable dual speed component: the dual speed component can be easily disassembled without disassembling the entire focusing seat to adjust the desired tactile sensation

4: Extra large pointed tooth handwheel: The diameter of the coarse adjustment wheel reaches 38 millimeters, and the diameter of the fine adjustment wheel is 28 millimeters, reducing the feeling of slipping when twisting by hand

5: 360 degree rotation: convenient for photography composition and visual inspection [try to fix the angle as much as possible to avoid affecting the optical axis focal plane and balance, especially after adding electronic adjustment]

Focusing stroke: 42mm (the focusing barrel has a stroke up to the 38mm mark, and there is still a 4mm stroke at the blue joint)

Weight: 710g

Minimum height: 62mm

Note:

1. There may be slight image drift during forward and reverse rotation [a common problem with traditional structure focusing seats, which can only be reduced but not eliminated]

2. Standard without 2-inch to 1.25-inch interface
