Optical Tube Assemblies (OTA)
The optical tube assemblies that we have on offer are refractor telescopes with decent apertures and superior quality optics. Their optics' high resolution and minimal optical disruptions (chromatic aberration) mean that they provide exceptional viewing of sky objects and that they are great for astrophotography.
The optical tube assembly is a great buy for astronomers looking for a telescope to customise or to add on to an existing system. If you can't find one that suits your preferences, you can contact us to ask for a quote and availability of the specifications that you're interested in.
