The new Olivon Off Axis Guider is the lowest profile off axis guider that we know. Despite this no compromise has been made with the function and operating comfort of this versatile Off Axis Guider.
Advantages of Off-Axis Guiding:

-- No mechanical flexure between main and guiding telescope can possibly ruin the tracking accuracy if you use an off axis guider.

-- The load for the mount is much reduced. There is no need for a guide scope and the setup will remain more compact.

-- You work with the main telescope's resolution and focal length, not with the typically lower resolution of a guide scope.

Advantages of the OAG 9:

The ultra-low profile design and the various available adaptations offer many unique advantages:

Can be used with correctors & DSLR:
The only Off Axis Guider that can be used between a coma corrector (or field flattener) and a DSLR camera without leaving the tolerance for the distance between camera and corrector.

Can be used with cooled CCD cameras:
The off axis guider provides enough space for filter wheels or filter drawers when using cooled CCD cameras.


Place the OAG behind the corrector:
The OAG is used between the corrector and the camera. Using an off axis guider in front of the corrector is not useful. The guide star would be distorted, the distances on both optical paths are too different and you might even get focusing problems with the main camera.
Behind the corrector you can avoid these problems, but this only works due to he low profile of the TS OAG!

Large Clear Aperture:
Compared with many simpler guiders the TS OAG not only has a shorter overall length, but also a larger clear aperture. A "T2 keyhole" can be avoided, resulting in better illumination for large sensor cameras up to 45mm diagonal.

Large choice of adaptations:
We offer a large selection of adaptors for all common cameras, coma correctors, field flatteners, filter wheels, ....

Canon EOS DSLR Camera Adaptation:

Hard to believe: From the threaded base of the Off Axis Guider until the camera's sensor the distance is only 56mm !!!!

This allows you to use the off axis guider with any coma corrector or field flattener while still maintaining the proper distance to the camera's sensor!
 


 

Specifications and Functionality:

The OAG 9 can be used with almost any telescope-adaptor-camera combination. We offer a variety of adaptations for almost all conceivable applications. We are of course happy to help you with your choice!


Specifications:

-- Telescope Adaptation ... 2" barrel base with M48 filter thread inside. (fits the M48 barrel extension)

-- Camera Adaptation ... M42x1 adaptation and Canon EOS bayonet

-- Side Turret Adaptation ... T2 thread for Autoguiding cameras. 1.25" eyepiece adaptation possible

-- All screws and threads are metric (M4)

Length:

The optical length of the off axis guider is only 9mm in the direction towards the main camera. (Not counting the length of the 2" barrel base)

Focusing mechanism for the guiding eyepiece or autoguider:

Each good quality Off Axis Guider needs to have a provision for focusing the guiding star individually. First you focus the main camera with the telescope's focuser. After that the guiding turret must offer its own focusing mechanism that allows you to focus the guiding camera (or eyepiece) without changing focus with the main camera! The TS Off Axis Guider offers a comfortable focusing mechanism:



The T2 disc on the guiding turret is the part to which the eyepiece or autoguider is connected. This disc can be moved along the turret, thus changing focus. The disc is fixed in position with either a slug screw or a thumbscrew. No spacer rings or other inconvenient means for focusing are needed.


Guide Star Search - made easy by the prism moving mechanism:

This is every bit as important as focusing: Finding a suitable guiding star. Simple off axis guiders only offer a "one-dimensional" ring around the target object for finding a guiding star. This is often done by rotating the off axis guider as a whole. The radial distance between the guide star and the object cannot be influenced directly. Often this limited area is not enough for finding a suitably bright guiding star, especially in telescopes with less than 10" aperture.

The OAG 9 allows you to move the prism radially. This increases the "one dimensional" ring to a "two-dimensional" disc, ultimately multiplying the number of available guide stars.

On a typical large sensor DSLR camera you can move the prism by up to 8mm - on smaller sensor cameras an even larger interval may be available.

Even with a 24x17mm sensor (e.g. in most DSLR cameras) you have at least 4mm range of movement even in the worst case position of the sensor, i.e. when the long axis diagonal of 29.4mm is pointed directly towards the prism. In all other orientations of the camera's sensor the movement range is larger. This 4mm+ range and the possibility to rotate the off axis guider provides a large enough area for finding a guiding star in all cases!

This is a brand new Olivon Off Axis Guider, that is being sold in the original box. Guider has an ultra low profile, only 9mm optical length. Provides better illumination for large sensors up to 45mm in diagonal. Includes 2" barrel nose with M48 filter thread. Also includes adapter ring for T-mount.
