TPO Focuser Collimation Ring for RC6 & RC8 Telescopes

Paired with your 6 or 8 inch RC telescope, the TPO focuser collimation ring allows the focuser and camera to be tilted ensuring they are square and parallel to the focal plane. Stars are perfectly collimated evenly across the entire field of view and slight errors that might be due to alignment of the baffle tube and focuser are easily corrected for superior imaging performance. Push/ pull adjustments are quick and easy to make in the field, the moment they are needed.
