As shown in Figure 5, the universal adapter includes the following components:
1- Mount-bracket
2 - Fixing-bracket (One of Model A/B/C/D/T)
3 - Shaft-converter (One of A-type or B-type)
4 - Bearing
5 - A5 Gear
6 - Screws

To fit different telescope models, universal adapter are divided into some sub-models, including:
1 - Adapter for FSQ106/TOA130-NFB
2 - Adapter for Epsilon/TOA130-NS
3 - Adapter for SkyRover 72ED
4 - Adapter for Sharpstar newtonian
The difference between different sub-models is that they use different fixing-bracket or shaft-converter or screws. And with some simple measurements, we can create more universal adapter sub-models to fit more telescopes.
The components contained in these adapters are shown in Figures 6, 7, 8, and 9 below.

Figure 7 Adapter for Epsilon/TOA130-NS

Figure 8 Adapter for Sharpstar Newtonian

Figure 9 Adapter for SkyRover 72ED
When using a universal adapter to install Oasis Focuser, the clamp used is 30mm uniformly. Therefore, after installing the universal adapter, it is very convenient for users to share Oasis Focuser among different telescopes.
