Important: The corrector can be connected to the focuser in two ways but the correct way is to ensure the long part points into the drawtube and the short part towards the camera.

Astrophotography Cameras:
An M48x0.75 thread is available on the back of the sturdy 2.5" focuser. The working distance from this thread to the camera sensor is exactly 55 mm making it ideal for all astro cameras and DSLR / SLR cameras.

The TS 61EDPH also provides a convenient connection for 2" nebula filters. All you need to do is simply unscrew the corrector from the focuser and you will find an M48x0.75 female thread on the telescope side. Simply screw in the nebula filter and then screw the corrector back into the focuser. The working distance of 55 mm still remains the same.

Mount Connection:
The CNC tube ring has a GP/EQ5 style dovetail bar at the base. You can attach the telescope to the appropriate saddle of various mounts, the dovetail also has a 1/4" photo thread which means the small APO fits just like a telephoto lens, directly on a photo tripod too.

Multifunction Carry handle:
The handle not only facilitates the mounting on a photo tripod, its also the base for further adaptions. The handle has a long hole and a 1/4" photo thread so you can mount a ball head onto it and mount a second camera in parallel. Next to the grab handle there is a viewfinder shoe for a finderscope or guidescope.
