TS-Optics adapter for TS-GPU & Baader MPCC to M54x1 female thread for screwing

TS screw adapter for Baader corrector and TSGPU to Newtonian focusers with M54x1 female thread

The Baader MPCC coma corrector and the TSGPU are widely used among astrophotographers. With this adapter, you can optimally connect the coma corrector to your Newtonian - without fear of tilting or distortion, absolutely safe and above all with very short paths. The corrector disappears completely in the drawtube. Only the connection thread on the camera side protrudes from the adapter. The distances from the camera thread of 55 mm are retained even with the adapter.

Connecting the corrector with the adapter to the Newtonian:

The coma corrector is screwed into the M48 female thread of the TS adapter.

The adapter is screwed with the coma corrector into the M54x1 thread of the focuser.

Afterwards, the camera can be connected via the matching adapters as before.

The adapter is suitable for the following telescopes:

The adapter is suitable for many Sky-Watcher telescopes equipped with a 2" Crayford focuser. The connection thread of the draw tube is a M54x1 female thread. When adapting to other focusers, please note the pitch. The 2" Crayford focuser UNCN2-G2 from TS-Optics, for example, has an M54x0.75 thread with 0.75 mm pitch.

The advantages of a screwed solution:

With the normal 2" Skywatcher adapter, two screws press on the 2" barrel of the coma corrector. Due to the locking groove of the corrector, tilting can easily occur. Blurred stars in the corners are the result. A screwed solution prevents this.

The metal screws slightly scratch the housing of the coma corrector, and may even distort the lenses if too much contact pressure is created. A screw connection, on the other hand, does not exert any pressure on the corrector.

With a screw attachment, a 100% fit on the optical axis is always guaranteed.

With a plug-in solution, the unit can also fall out of the 2" receptacle of the focuser at times when the screws become loose. This cannot happen with a screwed solution.
