By removing the front adapter of the ATIK 16200 camera, it is possible to fix (using several screws) directly the EFW3 filter wheel on the body of the camera. Then the off-axis guider is fixed to the body of the filter wheel through other screws. In this way a single block is created, perfectly rigid and stable, which occupies only 58,5mm of thickness from the camera sensor to the 54x0.75 female thread placed in front of the off-axis guider.
The off haxis guider has a T2 male thread to allow you connect many autoguide cameras. If you have a guide camera with 31,8mm diameter (like Lodestar, QHY5L-II or QHY5III) you just need to add a 31,8mm visual back, like in the picture below.
