Massive variable M48 extension with M63 intermediate thread
TS variable M48 Extension for setting exact focus distances - TSM48FL was developed by Teleskop-Service for accurately setting of distances from cameras to correctors. Due to the stable design, even accessories weighing several pounds can be held precisely. There is a large clear aperture of 45 mm - thus the adapter can also be used for full-frame size cameras.
When distances continuously vary between 20.5 mm and 31 mm, you can now lock them down by a stable, 5 mm thick locking ring. The locking ring has a lateral lever which allows reliable clamping, but also easy loosening after clamping, even when wearing gloves.
The adapter consists of three parts all of which can be used separately:
The telescope-side connector with an M48x0.75 thread (female) and a continuous M63x1 thread (male). This extends an M48 thread (male) to an M63 thread (male).
Massive locking ring with a continuous M68x1 thread (female) and a locking lever at the side.
The camera-side connection adaptor has a long M68x1 thread (female) and an M48x0.75 thread (male). It also doubles as an M48 connection adapter for all focusers and adapters with M63x1 threads (male).
Connection thread at telescope side: M48x0.75 thread (female) to 2-inch filter thread.
- Connection thread at camera side: M48x0.75 thread (male) to 2-inch filter thread.
- Length: Variable from 20.5 mm to 31 mm.
