The Techable buying guide

Choose telescope accessories that fit your setup

Compare eyepieces, mounts, filters and optical accessories by the change you want to make. Match the accessory to your exact telescope before ordering.

Change your view

For eyepieces and focal extenders, check barrel size, focal length and viewing requirements. A higher magnification is not automatically a better view.

Support & find targets

For mounts, tripods and finder scopes, check attachment points, equipment weight and capacity. Review power and control requirements for tracking systems.

Build an imaging setup

Reducers, flatteners, coma correctors and imaging filters have specific optical and spacing requirements. Check the telescope model and adapters required.

Physical fit is only the first check

Barrel diameter, threads and mounting connections must match. Optical spacing, load capacity and electronic compatibility can also determine whether an accessory works.

Questions before you choose

Will an accessory work with every telescope?

No. Check the exact product’s supported telescope models, barrel or thread size, required spacing and included adapters. A part that attaches physically may still be unsuitable for the optical system.

Can I use every filter for visual observing?

No. Filters can be intended for visual observing, photography or specific wavelengths. Follow the product’s intended use and instructions. Ordinary astronomy filters are not a substitute for properly specified solar-viewing equipment.
