Why should I replace the stock focuser on my William Optics FLT110?
For demanding astrophotography with heavy equipment, upgrading to a Starlight Instruments Feather Touch focuser provides superior load capacity and zero image shift. This adapter makes that upgrade possible, improving the reliability of your autofocusing and the overall rigidity of your imaging train.
Which Starlight Instruments focuser does this FLT110 adapter fit?
This adapter is designed specifically to mount any of Starlight Instruments' 3.0" Feather Touch focusers to the optical tube of a William Optics FLT110 telescope that was originally equipped with the DDG stock focuser.
Is installing this adapter on my FLT110 difficult?
Installation is straightforward for users comfortable with minor hardware changes. It typically involves unthreading the entire stock focuser assembly from the optical tube and securely threading this adapter in its place. The new 3.0" Feather Touch focuser then attaches directly to the adapter.
Will this adapter work with other William Optics telescopes besides the FLT110?
No. This adapter is custom-machined for the specific thread pattern and mechanical interface of the William Optics FLT110 (DDG focuser version). It is not compatible with other telescope models.
Does this adapter change the back focus of my FLT110 telescope?
The adapter is engineered to position the new Feather Touch focuser at the correct distance to maintain the telescope's intended back focus range. It replaces the stock focuser's mounting system, allowing you to reach focus with standard imaging accessories.
What is the benefit of a 3.0" focuser for imaging with my FLT110?
A 3.0" focuser provides a large, unvignetted light path, which is essential for illuminating large-format camera sensors, especially when using a focal reducer. This ensures bright, even illumination from corner to corner on your images, preventing dark corners on your final astrophotos.
If I am imaging the Andromeda Galaxy (M31) with my FLT110 and a large sensor camera, how does this adapter help?
When imaging a large target like the Andromeda Galaxy (M31), preventing field tilt from focuser sag is critical for achieving sharp stars across the entire frame. This adapter enables the use of a rigid 3.0" Feather Touch focuser, ensuring your camera sensor remains perfectly flat relative to the focal plane, which is essential for high-quality, wide-field images.
