DEMO, Celestron Focus Motor for SCT and EdgeHD, – 1 out of 2 models Review

What Makes DEMO, Celestron Focus Motor for SCT and EdgeHD, – 1 out of 2 models Stand Out?

The DEMO, Celestron Focus Motor for SCT and EdgeHD, – 1 out of 2 models promises to bring a new level of precision and convenience to focusing your Celestron telescope. Made by Celestron, this focus motor allows electronic, hands-free focusing of Schmidt-Cassegrain (SCT) and EdgeHD telescopes. The promise of remote focusing, multiple speed rates, and compatibility with a wide range of telescopes immediately piqued my interest.

As an avid astrophotographer, achieving perfect focus is a constant battle. The slightest vibration can ruin an image, and manually tweaking the focus knob in the dark, often while wearing gloves, is rarely ideal. The Celestron focus motor seemed like the perfect solution to dial in precise focus remotely, eliminating vibrations and maximizing image sharpness.

The unit arrives in a simple, functional box. My first impression was positive; the motor feels solid and well-constructed. It’s compact enough not to add significant weight or bulk to the telescope. Compared to using a Bahtinov mask and manually adjusting the focus knob, this felt like a quantum leap in efficiency.

My previous setup involved a DIY system using a stepper motor and a custom-built controller, which was clunky and unreliable. This Celestron unit promised a more integrated and user-friendly experience. I had been using a manual micro-focuser attachment on my SCT, but the electronic control and multiple speed rates offered by the motor were extremely appealing for finer adjustments. My initial excitement was high – the potential for sharper images and more efficient observing sessions was palpable.

Real-World Testing: Putting DEMO, Celestron Focus Motor for SCT and EdgeHD, – 1 out of 2 models to the Test

First Use Experience

I initially tested the DEMO, Celestron Focus Motor for SCT and EdgeHD, – 1 out of 2 models in my backyard observatory, using my Celestron EdgeHD 8″ telescope. The weather was clear, with relatively stable seeing conditions. The installation process was straightforward, taking only about 15 minutes with the included instructions.

The focus motor was initially powered via the AUX port of my Celestron Advanced VX mount. Controlling the focus using the mount’s hand controller was surprisingly intuitive. I also connected it to my laptop via USB for control through Celestron’s PWI software. The focus motor functioned smoothly, responding quickly to commands from both the hand controller and the software. I experienced no issues during the initial setup and testing phase.

Extended Use & Reliability

After several weeks of regular use, the Celestron Focus Motor has proven to be a reliable and valuable addition to my astrophotography setup. There are no noticeable signs of wear and tear despite frequent use. Cleaning is minimal, requiring only occasional wiping down of the motor housing with a damp cloth.

Compared to my previous manual focusing methods, the Celestron Focus Motor is significantly more precise and efficient. Achieving critical focus is now faster and easier, resulting in noticeably sharper images, especially when imaging faint deep-sky objects. The ability to adjust the focus remotely has virtually eliminated vibrations, and backlash compensation works perfectly to avoid any focus shift. It outperforms my previous DIY setup in every aspect.
