More About This Category
If the view is shaky or jumpy when the draw tube is racked in or out, or flexes when heavier eyepieces or accessories are introduced, your focuser can make observing almost impossible. A quality focuser should provide precise positioning of the eyepiece or camera to within .002 inches. Focusing should be smooth and easy, without any backlash, so the telescope doesn't vibrate or shake, even at higher magnifications. A decent focuser should be able to handle the weight of today's multi-element eyepieces, as well as a DSLR or standard CCD camera.
At High Point, you’ll find affordable rack and pinion focusers and more advanced Crayford focusers. We also carry highly precise electric and motorized focusers. These are excellent because they virtually eliminate vibration by removing the need to touch the telescope. Electric and motorized focusers may also come with a controller and/or different speed settings to bring convenience and variety to your viewing experience.
Enhancing Your Telescope Experience with Focusers and Focusing Accessories
While the optics might be the show's star, an excellent focuser is key to a smooth and enjoyable viewing or imaging experience. A high-quality focuser provides a stable, precise connection between your telescope and your eyepiece or camera, making fine adjustments a breeze. At High Point Scientific, we offer a diverse selection of focusers and focusing accessories to fit various needs and budgets. Our carefully chosen range ensures top performance, regardless of your astronomical goals.
The Importance of a Quality Focuser
A focuser adjusts the position of the eyepiece or camera to achieve sharp focus. An unstable focuser can cause a shaky or erratic view, making observation nearly impossible, especially at higher magnifications. A high-quality focuser accurately positions the eyepiece or camera to within .002 inches and supports the weight of heavy multi-element eyepieces or a DSLR camera without any flexing.
Key features of a high-quality focuser include:
Smooth Operation: Focusing should be effortless and without backlash, ensuring the telescope doesn't vibrate or shake.
Stability: A good focuser can support heavy accessories without flexing.
Precision: Accurate positioning is essential for sharp, clear views or images.
Types of Focusers
Rack and Pinion Focusers
Affordable and Reliable: These traditional focusers utilize a gear mechanism for smooth focusing and offer budget-friendly and dependable performance for general use.
Crayford Focusers
Advanced Precision: Crayford focusers use a friction roller mechanism, which provides higher precision and smoother operation than rack-and-pinion focusers. They are ideal for more demanding observational and imaging tasks.
Electric and Motorized Focusers
Vibration-Free Precision: Electric and motorized focusers eliminate vibrations by minimizing physical contact with the telescope during focusing. Equipped with controllers and adjustable speed settings, they offer enhanced convenience and versatility. These features make them indispensable for astrophotographers seeking precise and stable focusing capabilities.
Popular Focusing Accessories
Enhancing your telescope's focusing capabilities continues beyond the focuser itself. Various accessories can further improve your experience.
Micro Focusers
Starlight Instruments FeatherTouch Fine Micro-Focuser Upgrade: Designed for specific telescope models like the 11" Celestron SCT, this upgrade allows for both standard and 1/10th speed focusing, providing ultra-sharp views with minimal effort.
Helical Focusers
ZWO 1.25" Non-Rotating Helical Focuser: Perfect for astrophotographers utilizing the ZWO Off-Axis Guider (OAG), this tool enables precise focus adjustments without rotating the camera. It maintains the exact alignment of your imaging setup throughout the session.
Selecting the Right Focuser
Compatibility: Make sure the focuser matches your telescope model and fits well with your accessories.
Weight Handling: Verify that the focuser can handle the weight of your heaviest eyepieces and cameras.
Type of Observation: Consider if you'll use the focuser mainly for visual observations, astrophotography, or both.
Budget: Focusers vary widely in price, from budget-friendly rack and pinion models to high-end motorized options. Find one that fits your budget and meets your performance needs.
Enhancing your focus can elevate your astronomical observations and astrophotography. A top-notch focuser guarantees optimal views and sharp images by delivering smooth, precise, and stable focusing.
