Starlight Instruments 3.0" Adapter for Meade 16" SCT Telescopes
The Starlight Instruments 3.0" Adapter for Meade 16" SCTs provides the essential threaded connection for upgrading your telescope with a premium 3.0" Feather Touch focuser. This adapter features a 4.0"x16tpi female thread that attaches directly to the rear cell of the Meade 16" SCT and adds 2.3" of length to the optical path, ensuring a secure, flex-free foundation for heavy imaging equipment.
A Precision 4.0"x16tpi Interface for the Meade 16" SCT
This tube adapter is the critical component for mating a Starlight Instruments 3.0" focuser to the large-format rear cell of a Meade 16" SCT. Its precision-machined 4.0"x16tpi female threads guarantee perfect alignment and a rigid connection, eliminating the image shift and flexure common with standard Schmidt-Cassegrain focusing mechanisms.
By enabling the use of a high-end external focuser, this adapter allows you to achieve the critical focus necessary for high-resolution planetary imaging and deep-sky astrophotography. The adapter's 2.3" length must be considered when calculating back-focus for reducers and other accessories in your imaging train.

What is the purpose of this Starlight Instruments 3.0" adapter?
This adapter is designed to securely mount a Starlight Instruments 3.0" Feather Touch focuser onto the rear cell of a Meade 16" Schmidt-Cassegrain Telescope. It provides the correct 4.0"x16tpi female thread required for a rigid, stable connection.
Which specific Starlight Instruments focuser is this adapter for?
This adapter is specifically for the Starlight Instruments 3.0" Feather Touch focuser family, such as the FTF3015B-A or FTF3025B-A. It will not fit 2.0" or 3.5" focusers.
Will this adapter fit a Meade 12" or 14" SCT?
No. This adapter is specifically machined for the 4.0"x16tpi thread found only on the Meade 16" SCT. Smaller Meade SCTs use a different rear cell thread size and require a different adapter.
How does installing this adapter and a Feather Touch focuser improve my Meade 16" SCT?
Upgrading your Meade 16" SCT with this adapter and a Feather Touch focuser completely bypasses the telescope's internal mirror-focusing mechanism. This has two main benefits:
-
Eliminates Image Shift: The primary mirror remains locked, preventing the "image shift" or "mirror flop" that plagues SCT focusing.
-
Adds Fine Control: You gain the ultra-precise, dual-speed control of a Feather Touch focuser, which is essential for achieving sharp focus with heavy cameras and at high magnifications.
Is this adapter all I need to mount a 3.0" focuser on my Meade 16" SCT?
This adapter is the part that connects the focuser to the telescope tube. You will also need the Starlight Instruments 3.0" Feather Touch Focuser itself to complete the installation.
Does the Starlight Instruments 3.0" adapter allow the focuser to rotate once installed on the Meade 16" SCT?
Yes. Starlight Instruments focusers are designed to rotate a full 360 degrees within the tube adapter. Once this adapter is threaded onto your Meade 16" SCT, you can insert the focuser and then rotate it to any desired orientation for framing your camera or positioning your eyepiece, then lock it in place.
