2" T-2 Nose Piece for H3 by Beta — model 2408150

Beta 2" T-2 Nose Piece for H3 (model 2408150) is an optical adapter that provides a 2-inch (50.8 mm) barrel interface combined with T-2 (M42x0.75) threading to connect 2" eyepieces or instruments to an H3 T-2 assembly. The component is designed for precise mechanical alignment, stable optical coupling and repeatable mounting when integrating 2" accessories into optical trains that use T-2 connections.

Advantages

The adapter offers a standardized 2" barrel fit together with T-2 threads for versatile compatibility across telescopes, cameras and imaging accessories. Its construction ensures secure mechanical engagement and maintains optical axis alignment between connected parts. The part simplifies converting legacy 2" components to modern T-2 based systems without altering the attached instruments.

Suitable for

• Connecting 2" eyepieces to T-2 equipped focusers or adapters
• Integrating 2" filters, diagonals or optical accessories into T-2 imaging trains
• Adapting photographic cameras or CCD/CMOS imagers that accept 2" barrels to T-2 threaded adapters
• Use in amateur and semi-professional astronomy setups requiring stable mechanical coupling

Key specifications

• Barrel diameter: 2 inches (50.8 mm)
• Thread type: T-2 (standard M42x0.75 fine pitch thread compatible with T-2 systems)
• Material: metal alloy with machinings suitable for optical use (anodized finish expected)
• Mounting interface: 2" male/female barrel to T-2 threaded connection
• Function: mechanical and optical coupling between 2" components and T-2 systems

How to use

Insert the 2" barrel end into the receiving 2" focuser or accessory and secure it using the focuser's set screws or compression ring as applicable. Thread the T-2 side into the corresponding T-2 female thread of the H3 assembly until hand-tight, then make fine alignment adjustments as needed. Ensure threads engage smoothly and avoid cross-threading; use gentle torque to prevent damage. Verify optical centring and focus after mounting before commencing imaging or observation.

Usage recommendations

Before installation, check mating surfaces for debris and ensure threads are clean and dry. For repeatable results in imaging, confirm that the adapter is fully seated and locked and verify backfocus distance required by your camera or eyepiece. Avoid over-tightening and protect the 2" barrel and T-2 threads with caps when not in use.
