SVBONY SV106 Guide Scope with Helical Focuser Finder and Guide Scope Multi-Use for Astronomical Telescope (60mm)

I have been using this as a astrophotography guidescope for while now on two of my telescopes. It's helical focuser makes it easy to quickly focus for use. Once focused I have not had to change it (Although I check occasionally). It provides a good clear image for guiding my systems.

I received this scope quickly and have not put it to use yet because the skies have been cloudy and sky viewing is limited. I do already have the 50mm version of this and it works great as a guide scope. It is simular in weight, size but with a longer focal length. All parts was there and assembly was quick and easy. I will be using this with a 90mm refractor telescope and ASI224 guide camera.

My primary use for this is as a guide scope. There are some problems that need to be addressed. First, the rear ring mount, if placed in the original position with the front mount against the lip on the dew shield interferes with the draw tube lock. You have two solutions - slide the scope back and secure the front ring on the dew shield or drill a second mounting hole to move the rear ring forward. I chose the 2nd for a reason.The objective is secured by the dew shield. You unscrew the dew shield maybe 5 - 6 mm and you can have the objective in your hand. Or on the floor. That's why the dew shield is not an especially good way to support the front of the scope.There is not enough back focus to use the ZWO120mm camera without some extension. The camera does come with a 22 mm extension and that is enough to get you to focus. Note that the camera cannot be fully seated but is about 1/2 way out of the focuser with everything extended. It should work well enough, but it's not quite ready to go out of the box.It does focus well enough, although the helical portion is a bit stiff. The draw tube has a scale to use different gear more easily. The image seems decently sharp.

Precise focuser is quite handy, and optical quality is good. Make sure your mount won't get unbalanced by the scope, I had to strap a water bottle to the other end of my newtonian so it stayed where it was with the camera attached. The pair of rings with a total of 6 screws holds the scope firmly and is easy to adjust.

I have been very happy with every purchase I have made so far from SVBONY. Now, I am careful about the things I buy, but honestly they have delivered on quality and the Price/Value tradeoff is unbeatable. This guide scope (I use it as such most of the time) is also a pretty good wide field telescope. I have not used it for visual observing, only with Astro cameras, but I have been absolutely satisfied with it in both types of use, as a guide scope for my Meade 8” LX90 OTA and my Astro Tech AT115EDT, and as a wide field scope. The cameras I have used it with so far are my ZWO ASI220mm Mini (guide scope) and my ZWO ASI533MC Pro. No problems with either of them.

Sencillo, pero a la vez de buena calidad. Lo recomiendo.

Nice addition to my sv503 102ed

As an autoguider scope, this thing is excellent for the money. I have it paired with a ASI220mm Mini and get nice sharp stars in PHD2. It's not the best-built telescope out there, but the aperture for the price is hard to beat.
