What is the purpose of the Starlight Instruments 3.5" Adapter for the William Optics FLT178?
This adapter is designed for one specific task: to create a secure, direct threaded connection between a Starlight Instruments 3.5" Feather Touch focuser and the optical tube of a William Optics FLT178 telescope. It ensures perfect mechanical and optical alignment between these two premium components.
I am upgrading my William Optics FLT178 to a 3.5" Feather Touch focuser. Is this the only part I need?
Yes, this adapter is the correct and necessary component to mount a 3.5" Feather Touch focuser onto your FLT178. You will need the focuser itself and this adapter to complete the installation.
Will this adapter introduce any flexure when I attach my heavy imaging camera to the FLT178?
No, this adapter is engineered to prevent flexure. It is machined from high-grade aluminum to provide a rigid, non-flexing connection that can support heavy imaging trains, including large cameras, filter wheels, and off-axis guiders, without compromising the optical alignment of your FLT178.
How does this Starlight Instruments adapter attach to the telescope and the focuser?
The adapter features precision-cut threads on both ends. One end threads securely onto the rear cell of the William Optics FLT178 optical tube, and the other end threads directly into the body of the 3.5" Starlight Instruments focuser, creating a single, solid unit.
Why should I use this specific adapter for my FLT178 instead of a generic one?
This adapter is custom-machined by Starlight Instruments specifically for the FLT178 and their 3.5" focuser. This guarantees perfect thread compatibility, precise optical spacing, and the same high-quality materials and finish as your Feather Touch focuser, ensuring a professional and reliable fit that a generic adapter cannot match.
Does the Starlight Instruments 3.5" Adapter require any special maintenance?
No, the adapter requires no maintenance. It is a solid-state component made of anodized aluminum. Simply keep the threads clean and free of debris during installation to ensure a smooth and secure connection.
