Starlight Instruments 2.0" Adapter for Astro-Physics Stowaway
This Starlight Instruments 2.0" Adapter provides the essential mechanical link for upgrading pre-2018 Astro-Physics Stowaway refractors with a 2.0" Feather Touch focuser. It creates a rigid, threaded connection point engineered to the precise tolerances required for astrophotography.
A Custom Fit for Pre-2018 Astro-Physics Stowaway Telescopes
This adapter is not a generic-fit component; it is specifically designed to match the tube and mounting threads of Astro-Physics Stowaway refractors manufactured before 2018. The design ensures perfect axial alignment and a no-flexure connection, which is critical for maintaining sharp focus across the image plane, especially with modern, high-resolution sensors. By creating a solid metal-on-metal interface, it eliminates the potential for image shift or tilt that can compromise lesser mounting solutions.
Unlocking the 2.0" Feather Touch Focuser Ecosystem
Installing this adapter opens your Astro-Physics Stowaway to the full capabilities of Starlight Instruments' 2.0" focusers. You gain access to the acclaimed 10:1 dual-speed fine focusing mechanism, robust load-bearing capacity for heavy cameras and filter wheels, and the ability to add motorization with systems like the HSM or PDMS for automated, computer-controlled focusing. This upgrade transforms the Stowaway into an even more capable imaging platform, delivering the focusing precision that modern astrophotography demands.

Which focusers work with this Starlight Instruments 2.0" Stowaway adapter?
This adapter is for use with the FTF2025BCR 2.0" Feather Touch focuser. It provides the correct threading and mechanical interface for these focusers.
Is this adapter compatible with Astro-Physics Stowaway models from 2018 or later?
No. This adapter is specifically engineered for pre-2018 Astro-Physics Stowaway models. Astro-Physics may have changed the tube threading or focuser mounting design in later production runs, so you must verify your telescope's manufacture date before purchasing.
How does this 2.0" adapter improve imaging with a pre-2018 Astro-Physics Stowaway?
The primary benefit is that it allows you to install a Feather Touch focuser. This provides two key advantages for imaging:
-
Precision Focus: The 10:1 fine focus knob allows for extremely small, repeatable adjustments necessary to achieve critical focus with high-resolution cameras.
-
Load Capacity: A Feather Touch focuser, securely mounted with this adapter, can handle heavy imaging trains (camera, filter wheel, off-axis guider) without sagging or shifting, which is essential for long exposures.
Does installing this Starlight Instruments adapter require permanent modifications to my Stowaway?
It is a scope-specific adapter with a 3.6" x 24 TPI thread on the telescope side. Installation steps are not described, so ask us before ordering if you need those details.
What is the main reason to upgrade the focuser on a pre-2018 Astro-Physics Stowaway?
While the stock focuser on an Astro-Physics telescope is of high quality, upgrading to a Starlight Instruments Feather Touch provides superior fine-focus control and opens the door to electronic and automated focusing. For demanding imagers seeking to eliminate any potential mechanical variable and achieve perfect, repeatable focus via software, the Feather Touch system is the industry standard.
Can I use a 2.5" or 3.0" Feather Touch focuser with this adapter for my Stowaway?
No, this adapter is specifically sized and threaded for Starlight Instruments' 2.0" focuser bodies. It will not fit the larger 2.5", 3.0", or 3.5" models.
