Impressive performance

Put it on my TS60/360 to use it primarily as electronic finder scope and for plate solving. Lightweighted but solid and compact with sharp picture. Have to substract one star for the fact, that it cannot be fine aligned. One millimeter more space in the rings and a cross screw connection would improve it significantly and it could then also be used as finder scope in combination with an illuminated eyepiece and diagonal prism.

Perfect Guider Scope, but not to use as simple finder without extension!

Astonishing quality for a good price. But you can only use it with a camera! If you want to use it just with bare eyes, you need extras, focus extender, focuser, eyepiece. Please Svbony tell your customers which extras to take for that use and give the links to the products in your shop! And thanks a lot that you are packing so environment-friendly without too much waste!

Pocket Rocket

1. Features precise helical focus adjustment with convenient thumbscrew focus lock

2. Compact and with a built-in helical focuser for precise focusing of potential guide stars

3. UNC(1/4-20)-mount equipped for secure threaded attachment of autoguide devices

4. SV165 can ensure that the main mirror accurately tracks the celestial body to be observed and matches perfectly with today's sensitive autoguiding cameras for easy guide star acquisition

5. Will need an extension tube for extra focal length if you want to use eyepiece.
