How does the FTM-C6 Micro Focuser improve on the stock Celestron focuser?
The stock focuser on an SCT moves the entire primary mirror, which can cause the image to shift or "flop" during adjustment. The Starlight Instruments FTM-C6 replaces this with a high-precision, external mechanism. This eliminates image shift for a perfectly stable view and adds a dual-speed fine-focus knob for making the tiny adjustments needed for sharp planetary imaging and viewing.
Will the FTM-C6 help me get a sharper focus on Jupiter with my Celestron 6" Evolution?
Yes, absolutely. Focusing on planets like Jupiter or Saturn at high magnification requires extremely small, precise adjustments to see fine details like cloud bands or the Cassini Division. The stock focuser often moves in steps that are too coarse. The FTM-C6's fine-focus knob allows you to dial in perfect sharpness without overshooting the mark, making a significant difference in perceived detail.
My Celestron 6SE is a few years old. How can I be sure the FTM-C6 will fit before ordering?
You need to perform two quick checks. First, measure the outer diameter of the flange on your current focuser knob where it attaches to the telescope's rear cell; it should be either 1.5" (38mm) or 1.6" (40.6mm). Second, look at the rear cell itself. If it's a flat surface, you need the standard focuser. If it has a triangular pattern, you need the "CPC" version.
What tools are needed to install the FTM-C6 Micro Focuser?
Installation is straightforward and typically only requires a small hex wrench (Allen key) to remove the stock focuser knob and attach the Feather Touch unit. The process is non-invasive and can be done in minutes with the telescope tube positioned horizontally.
Are there any Celestron 6" telescopes the FTM-C6 will not fit?
Yes. Besides the flange size and rear cell pattern differences, this micro focuser cannot be installed on very old Celestron SCTs that use a C-clip on the internal focus shaft to hold the mirror. This is uncommon on modern scopes, but it's a known limitation for vintage instruments.
Can I motorize the FTM-C6 Feather Touch focuser later?
Yes. The Feather Touch Micro Focuser is compatible with Starlight Instruments' motor systems, such as the Handy Stepper Motor (HSM20). This allows you to add precise, automated focusing for astrophotography using control systems like the Focuser Boss II or Electronic Focusing System (EFS).
