  • The Starlight Xpress Slimline Off Axis Guider was designed to attach to the SX USB Filter Wheel.
  • The OAG prism can be adjusted by turning a easy to grab locking thumb screw, and the focal position is also adjustable.
  • For instances where the camera set up creates a longer than normal path length, we recommend the Starlight Xpress package that includes the Slimline Off-Axis Guider and a 30mm extension tube.
  • If you'd like to attach the Slimline OAG directly to the camera, check out the SX Slimline OAG Kit for direction connection to a Trius or SXVR camera.

    6. Place the threaded adapter on to the OAG and fix it in place with the 3 M2.5 x 5 panhead screws which you originally removed.


Setting Up the Autoguider...

    1. Fit your camera to the rear of the filter wheel and then fit the filter wheel to the rear of your telescope.
    2. Using the main imaging camera, take a series of images and adjust the focus of your telescope until the image is in focus.
    3. Screw the Lodestar or SXV-Autoguider to the threaded section of the top of the OAG and start to take images with the autoguider.
    4. Move the autoguider up and down the shaft until you achieve focus.
    5. Once you have achieved focus, lock the set screws.
    6. Your autoguider and main imaging camera are now par-focal and the system is ready to use.

Product Questions

Is the Slimline OAG compatible with the Orion Starshoot Autoguider, or will I need a C-thread to T-thread adapter?

I purchased this OAG and can't get it to focus with a SSAG Pro Mono. This guider is a bullet style that look like the QHY5L II. Do I need an extension tube? The camera screws in to the OAG fine but w/n focus in PHD. Thanks
