Focador de Astronomia
Acessórios de focagem de precisão para telescópios astronômicos e escopos de guia, projetados para substituir mecanismos de focagem lentos ou imprecisos por ajuste suave e de alta resolução.
The Astronomy Focuser range covers 18 catalogue items. Models in this range include K008 1.25 Inch Double Helical Focuser for Guider Finder Fcope; K007 1.25 Inch Double Helical Focuser with M31 to 2" Adapter; K006 2 Inch Fine Adjustment Seat for Astronomical Telescope; K005 Double Spiral Focusing Seat External T-mount Ring for Telescope. Every item is listed with the specification published for it, so a model can be compared on working distance, magnification, interface and fitment rather than on a description.

Ver DetalhesWhat Goes Wrong Without the Right Astronomy Focuser
- A sluggish or loose focuser makes it hard to achieve sharp focus on faint stars or planetary details
- Fixed focus mounts prevent fine-tuning during long-exposure astrophotography
- Inconsistent focus travel across different telescope models leads to setup delays and misalignment
- Low-precision focusers cause image drift during tracking, especially with heavy camera payloads
- Non-rotating focus seats limit access during high-altitude observations or polar alignment
Quem Compra Desta Categoria
- Amateur astronomers doing visual observation and astrophotography
- Professional observatories requiring repeatable focus settings
- Telescope builders and repair technicians upgrading legacy focus systems
- Users of guide scopes and finder scopes needing precise alignment
- Users of telephoto lenses adapted for planetary or lunar imaging
Por Que Estes Itens
- Double helical and double-threaded mechanisms provide fine 0.1mm focus steps for precise adjustment
- All-metal construction ensures durability and zero flex under load during long exposures
- Rotating focus seats allow access from any angle, useful during high-altitude or polar alignment sessions
- Universal 1.25 inch and 2 inch interfaces fit most telescope and guide scope barrels
- Adapter options (M31 to 2", M42, T-mount) allow integration with cameras, guides and eyepieces
Onde Estes São Usados
- Adjusting focus on a faint star during a deep-sky imaging session with a 2-inch focuser
- Aligning a guide scope with a main telescope using a 1.25 inch double helical focuser
- Mounting a CCD camera on a T-mount ring with a double spiral focuser for planetary work
- Fine-tuning focus on a Schmidt-Cassegrain telescope using an internal thread adapter
- Using a dual-speed focuser to quickly rough-focus and then fine-tune during live view
Antes de pedir

- Confirme a dimensão da interface contra o equipamento que já possui antes de encomendar
- Enviar a tarefa, bem como o número do modelo para que a configuração possa ser verificada
- Solicitar confirmação por escrito de qualquer valor de que uma proposta ou auditoria depende
Perguntas frequentes
Will this focuser fit my telescope's focuser barrel?
It fits if your telescope has a 1.25 inch or 2 inch focuser barrel. Check the inner diameter of your current focuser barrel and match it to the product's interface size.
What is the difference between single speed and dual speed focusing seats?
Single speed provides one gear ratio for focus adjustment. Dual speed uses a gear train to offer both coarse and fine adjustment in one mechanism, allowing fast initial focus and precise final tuning.
Can I use a rotating focuser on a telescope that's mounted vertically?
Yes. 360° rotating focus seats allow you to adjust focus from any angle, which is useful when the telescope is pointed high or in a fixed mount.
Are these accessories made of metal?
Yes. All models are constructed from full metal, ensuring rigidity and long-term durability under repeated use.
Do I need to buy a separate adapter for my camera or eyepiece?
Some models include adapters (like M31 to 2", T-mount, M42). Check the product details for included interfaces. Others require separate adapters based on your camera or eyepiece mount.
