Will this Starlight adapter fit any William Optics FLT98?
No. This adapter is specifically made for the William Optics FLT98 model that has a white optical tube and a gold stock tube adapter ring. William Optics has produced different versions of their telescopes over the years with varying mechanical specifications. You must verify your telescope version before purchasing to ensure compatibility.
Which Starlight Instruments focuser is this adapter for?
This adapter is designed to connect a Starlight Instruments 3.0" Feather Touch focuser to the specified William Optics FLT98 telescope. It will not work with 2.0", 2.5", or 3.5" Feather Touch models.
Why do I need a specific adapter for my FLT98 telescope?
Telescopes like the William Optics FLT98 use proprietary thread sizes on the rear of the optical tube. A custom adapter is required to create a rigid, perfectly centered, and tilt-free connection between the optical tube and a high-payload aftermarket focuser like the 3.0" Feather Touch. This is essential for astrophotography, where any mechanical flexure can ruin an exposure.
Is installing this FLT98 adapter difficult?
Installation is typically straightforward for users comfortable with basic telescope hardware. It involves carefully unthreading the stock focuser from the telescope's tube adapter ring and then threading this custom adapter in its place. The 3.0" Feather Touch focuser then attaches to this adapter. Always refer to the Starlight Instruments focuser manual for detailed installation instructions.
I have an FLT98 with a red tube. Can I use this adapter?
No, this adapter is confirmed only for the white tube version with the gold trim ring. Different color schemes or production runs of the FLT98 may have different mechanical threads or dimensions, meaning this adapter would not fit. You would need to contact Starlight Instruments or a dealer to find the correct adapter for a different FLT98 model.
What is this Starlight Instruments adapter made from?
Starlight Instruments machines all of their components to extremely high tolerances, typically from high-grade, black-anodized aluminum. This ensures a durable, non-reflective surface and a perfect match to the build quality of their Feather Touch focusers.
