Omegon Helical Focuser - Always precisely in focus, even with planets
The Omegon 2″ helical focuser helps you hit the focus point exactly. Especially in lunar and planetary photography, this makes a world of difference. You calmly turn to the perfect focus, without jerking or backlash. This keeps details sharp and rich in contrast.
More control with minimal movement
This spiral focuser works with extremely small increments. Each movement is controlled and fluid. That means you won't shoot past the focus point. Ideal at high magnifications, where precision is everything.

Fits virtually any telescope
You simply insert the helical focuser into any 2″ focuser, just like an eyepiece. No screws. No complicated assembly. Suitable for refractors, Newtons and also Schmidt-Cassegrain telescopes. Plug in and you're ready to focus.
Focusing with feeling, even with gloves
The large swivel mechanism fits comfortably in the hand and works smoothly. Even in the cold or wind, you continue to work accurately. The stepless movement keeps your image stable while you focus.

Remembering focus for later
The built-in scale shows you exactly where your focus is. Found the perfect point? Memorize the position and you'll find that focus immediately later. Each mark represents just 0.1 mm of displacement. That gives confidence and repeatability.
Ready for your camera
On the camera side is an M48 thread. This allows you to easily connect your camera. The focuser can support up to 4 kg, so even heavier cameras remain stable and neatly in place.
What this means to you:
✓ Accurate focusing on moon and planets
✓ No backlash, no shocks
✓ Quick upgrade without assembly hassles
✓ Focus easy retrieval
✓ Suitable for many telescope types
