Starwave 50mm Guide Scope with a 1.25" non-rotating Micro focuser, OTA, rings, stalk, and UNIFBR base
Focal length is 206.6mm (F4.1)  which is perfect for autoguiding a small refractor.
The focuser has a 1.25" ID push-fit adapter with brass compression ring, allowing use of auto-guiding cameras or 1.25"  eyepieces.
The indexed micro-focuser can be locked, enabling the eyepiece or camera to set at the correct focus-point.
Because the focuser does not rotate, the guide camera is easier to focus and maintain alignment on-target.
The rear of the focuser also includes a T2 thread to allow the addition of extensions. 
The finder stalk is compatible with most finder scope brackets on the market, but also includes a universal finder bracket (product code UNIFBR), with a cross-slotted hole pattern to fit most telescopes.
To attach the finder scope to dovetail bars, remove the stalk by means of the two set screws.
NOTE:  Eyepiece is not included with this model.
