Svbony SV106 50mm and 60mm Guide Scopes with Helical Focuser

Nice guide scope

Using on a Nexstar 6SE to improve auto guiding when F/7 or F/10. Works very well. Using the 60mm size for extra light. Focuser works very well and the image is nice and clear in the guide camera. No complaints

Excellent guide scope

I've use the 50mm as a guide scope for 420 mm 72ED and the 60mm for my 714 mm ED102 and both perform very well.

These guidescopes are well made and have very nice lenses. The cost is very real for what you receive.
