Starlight Instruments 2.5" End Cap for Vixen VC200L Telescope
The Starlight Instruments 2.5" End Cap provides a direct, secure threaded attachment for the Vixen focal reducer to a 2.5" Feather Touch focuser on a Vixen VC200L telescope, ensuring rigid alignment for the non-HD version of the reducer.
A Secure Threaded Connection for 2.5" Feather Touch Focusers
For astrophotography with the Vixen VC200L, a rigid, threaded connection is critical to prevent tilt and flexure. This 2.5" end cap replaces the standard compression ring on your Feather Touch focuser, allowing you to directly thread the Vixen focal reducer into the optical train.
Starlight Instruments machines this adapter from high-quality aluminum to maintain perfect alignment. Please note this end cap is specifically for the standard Vixen threaded focal reducer and is not compatible with the Vixen Telescope Focal Reducer HD.

What is the purpose of the Starlight Instruments 2.5" End Cap for the Vixen VC200L?
It provides a secure, threaded connection between a 2.5" Starlight Instruments focuser and the standard Vixen focal reducer, eliminating potential flexure from compression fittings. This is essential for astrophotography.
Will this end cap work with my Vixen Telescope Focal Reducer HD on my VC200L?
No. This end cap is explicitly designed for the standard Vixen threaded focal reducer. It is not compatible with the Vixen Telescope Focal Reducer HD model.
How does this Starlight Instruments end cap improve my imaging with a Vixen VC200L?
By creating a direct threaded connection, it ensures the focal reducer and camera are held rigidly and perfectly square to the optical axis. This minimizes sensor tilt and image shift, which is critical for achieving sharp stars across the field, especially when imaging faint objects like the Andromeda Galaxy (M31).
Do I need special tools to install this 2.5" End Cap on my Feather Touch focuser?
No. Starlight Instruments end caps are designed to be easily swappable. You typically just unthread the existing end cap (like a 2" compression ring) and thread this one on in its place.
Is this end cap made of plastic or metal?
The Starlight Instruments 2.5" End Cap for the Vixen VC200L is machined from high-quality aluminum for maximum rigidity and durability, matching the build quality of their Feather Touch focusers.
Can I use this end cap to attach other accessories besides the Vixen focal reducer?
This end cap is designed with specific threads to match the Vixen focal reducer for the VC200L. It is not a general-purpose adapter and is unlikely to fit other threaded accessories.
