What is the purpose of the Starlight Instruments 3.5" Adapter for the Takahashi FS128?
This adapter serves as the mechanical interface to connect a Starlight Instruments 3.5" Feather Touch focuser to the optical tube of a Takahashi FS128 telescope. It replaces the stock focuser mounting hardware, allowing for a secure, direct attachment of the upgraded focuser.
Which focuser is this adapter designed for on my Takahashi FS128?
This adapter is specifically designed for the Starlight Instruments 3.5" Feather Touch focuser (FTF35xx series). It is not compatible with their 2", 2.5", or 3" focusers. You must use this adapter to install the 3.5" model onto your Takahashi FS128.
Is this adapter made by Starlight Instruments or Takahashi?
This adapter is designed and manufactured entirely by Starlight Instruments in the USA. It is machined from high-quality aluminum and finished to their exacting standards to ensure a perfect match with their focusers and the Takahashi telescope.
How does this adapter attach to the Takahashi FS128 OTA?
The adapter is designed to thread or bolt directly onto the rear cell of the Takahashi FS128 optical tube where the original stock focuser was attached. The 3.5" Feather Touch focuser then attaches to the adapter, creating a solid, integrated unit.
Will using this adapter with a 3.5" Feather Touch focuser improve my astrophotography with the FS128?
Yes. The primary benefit is providing a rigid, non-flexing platform for your imaging train. A 3.5" Feather Touch focuser can handle significantly more weight than a stock focuser without sagging, which is critical for maintaining sharp stars across the field, especially during long exposures with a heavy camera and filter wheel on your Takahashi FS128.
What material is the Takahashi FS128 adapter made from?
The adapter is machined from high-quality aluminum for a combination of strength, rigidity, and light weight. It features a durable anodized finish to protect against corrosion and wear.
