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).

Connections:

• 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.

• With this variable extension tube (20.5 mm to 31 mm lengths), you can exactly set the working distance and mount even very heavy cameras!
• 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.
• Massive locking ring has a lateral lever, making the needed distance easy to maintain, and is possible even when wearing gloves. No tools required.
• It includes a useful intermediate thread M63x1 - so the TSM48FL can also serve as transition adapter to M63x1.
• There is a large clear-aperture of 45 mm - thus the adapter can also be used for full-frame size cameras.
