An off-axis guider is a brilliant invention. This device sits in the 2-inch focuser in front of the camera. A small prism directs a little light from the telescope into a separate tube - where your guide camera or crosshair eyepiece is attached. This makes it possible to instantly correcting any tracking errors during the extended period over which your camera is exposing the image - for perfectly round stars!
The advantages: 1) lets you take beautiful astronomy photos with round stars. 2) for refractors, SCs, MAKs and RC telescopes. 3) off-axis guider only 24mm in overall length - very compact. 4) robust yet light. 5) 45mm optical transmission - full illumination, even with large chips. 6) micro-focusing - especially smooth helical focusing with 0.05mm accuracy. 7) 75mm of back focus.
The connections: Easy to adapt - the Astromania off-axis guider has an M48 thread on the telescope side and an additional socket for 2 inch eyepieces. The accessory has three screws and a flat M48 adapter for connecting your camera. The advantage - you can rotate your camera at any time and find the optimum orientation for the astronomical object you are exposing.
Exact micro-focusing with 10mm travel - for auto-guider or crosshair eyepiece: A small prism directs light into the control unit of your guider- into a 1.25-inch helical focuser. Now insert your auto-guider or a crosshair eyepiece. With the generous 10mm of travel allows you will find the optimum sharpness for your guide star. Impressive - this special helical focuser can be adjusted to 0.05mm using the super fine scale. So you can always find the precise focus point very quickly.
The new Astromania 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. mechanical flexure between main and guiding telescope can possibly ruin the tracking accuracy if you use an off axis guider.
1) 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. 2) 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 Astromania 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 Astromania OAG!
Large Clear Aperture: Compared with many simpler guiders the Astromania 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.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.
