Starlight Inst. Feathertouch SCT Microfocuser for CPC & EdgeHD 1100

The Feathertouch SCT MicroFocuser by Starlight Instruments provides the smoothest control for fine focusing Celestron CPC and EdgeHD 11-inch telescopes.

Two focus knobs allows for standard or 1/10th-speed focusing, making the MicroFocuser extremely accurate. Excellent for both imaging or visual observing, this focuser is precision-machined and anodized black with a brass fine-focus knob.

The SCT MicroFocuser is easily installed in place of the original focus knob on Celestron CPC & EdgeHD 11-inch telescopes.

This model is not compatible with other 11-inch SCT's, however.

An upgrade you won't regret

A little pricey, but this upgrade will completely transform your viewing experience. Excellent quality with silky-smooth and precise movement. DO NOTE: although this model says it is for the CPC & EdgeHD, it may also be the model you need if you have a recent C11-XLT. Check Starlight Instrument's web site to be sure before you order.

Outstanding product

Once installed, the focuser performs flawlessly. The high level of workmanship is obvious, and this product is worth every penny paid. I did have questions while performing the installation and Starlight Instruments answered all of them over the phone and completely to my satisfaction. On my 11 inch Edge HD OTA, I found lots of grease used by Celestron. This was not forwarned in the installation instructions. Other than that, the installation was easy and just as the instructions showed. I am very impressed by this product and look forward to many years of usage.

Excellent craftsmanship - Smooth as silk

The fit and finish of this focusing aid is really excellent. The action is silky smooth. The direct connection to the focusing shaft of the scope makes the whole assembly very rigid and stable. Almost as if it were original factory equipment except better!

Silky smooth!

I took Brad's advice and got one of these for my CPC 1100 and I'm glad I did. It arrived today, took less than 15 minutes to install. (The instructions are clear and include photos at every step! I did a quick test on a distant daylight object and it worked perfectly. When you install the stop be sure the half-inch flats are in toward the scope, as shown in the photo. Also, if the focus knob seems tight when you're done, back off the three collar screws a bit until they are slightly snug. That should give you the same feel on the black knob as the original focuser. After all that, it even looks good - REALLY WORTH EVERY PENNY.

Worth the wait

It took awhile to get it, but it was well worth the wait. The fit and finish is top notch, and the action is as smooth as silk. Is it worth spending the extra dough on an item you'll touch every time you use your scope?....I think so.

Worth every penny

The CPC 1100 is tail heavy to start, so adding a rear mounted SCT focuser from W/O really complicated things. The W/O focuser was wonderful in use and craftmanship, but compounded the balance issue even with a Losmandy rail and weights. Enter the availability of the Feathertouch after waiting about 6 months for production issues to be solved. No balance issue, milder mirror flop at coarse focus, precision fine focusing and WORTH EVERY PENNY.
