The off-axis guider offers your a simple method of autoguiding your telescope for astrophotography. There is no need to mount a guidescope, rather a guiding camera tracks stars which are deflected from the telescope's optical path close to the imaging camera's sensor.
An advantage of this method is that the guide stars are located within the area of sky close the astrocamera. So you track the stars which are next to your desired object and avoid errors caused by differential flexure and guidescope misalignment.
The Elite Drawer OAG Kit combines the functionality of an off-axis-guider and a filter drawer in a single compact accessory.
- The prism’s height can be adjusted to suit the image circle: 7.5 to 19 millimetres of adjustment from the centre of the image.
- The smooth-running worm gear focuser allows precise focusing of the guide camera.
- The filter drawer accommodates an M48 filter and is held securely in place within the housing by a magnet. It enables quick filter changes whilst maintaining the OAG’s compact dimensions.
The set includes adaptors for M48, M54 and M68 telescope mounts, as well as M48 and M54 mounts for the camera side. This means that this special off-axis-guider should be adaptable to most common telescopes and cameras.
