Astromania Off-Axis Guider with Micro-Focusing - for Successful Astronomy Photos Without A Guide Scope

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..
