Our 60mm CompactGuide scope is simultaneously both a finder that a guide scope! It offers, at a great price, with an achromatic lens 60mm diameter and 240mm focal length (f/4), PLUS 80mm support rings (each with 3 screws with nylon tip) and a non-rotary helical focuser with connection for 31,8mm accessories and extension to allow you to reach the focus point both with eyepieces (for use as a finder) and with guide cameras (for use as a small guide scope).
Designed for use with many guide cameras (which can be inserted in the 31.8mm focuser connection or screwed on the T2 thread of the focuser), it can be used as a great optical finder adding a 31,8mm diameter eyepiece! The 60mm CompactGuide scope has a precision helical focuser that keeps the orientation of the connected camera. In fact, by acting on the focus mechanism, the camera does not rotate and this feature is essential for proper use with autoguiding software. The precision helical focuser has a 10mm travel.
In the box of 60mm CompactGuide scope with PLUS 80mm guide rings you will find also 2 additional plates that you use when you install the guide scope above the EAGLE. By adding these plates you will have a flat base for optimal connection with the 4 screws M5x12 that comes in the box.

- very much like the convenience of the brighter stars compared to a 50mm finder
- can using just a normal eyepiece easily find targets directly onto a CCD image of only 25’ to 20’.
Using an 18mm ocular I look into the finder from a distance where the image narrows down to only its center. Then I observe that the finder body also aligns at the center of the PLUS Guide Rings. If the finder is aligned with the scope, whatever is in the finder, will appear in the image that I have set to exposure continuously for a few seconds on 3x3 binning and autostretch. If the target doesn't have any 'hopping starts' immediately to it, I use further out hopping stars normally, and then make sure that as I move backwards away from the finder the narrowing image centers on the targeted location. This is also the way I use to align the finder.
