SVBONYSV106 Guide Scope with Helical Focuser Finder and Guide Scope Multi-Use for Astronomical Telescope (60mm)

I did not buy this to use as a tracking scope but to use with my C90 to take photos of the Sun, Moon, and objects such as the Pleiades, & Orion's nebula. With a much shorter focal length than the C90 it gives less magnification and a wider field of view than my C90. It is well made, well packaged and I think it is a very good deal for the price. It can also be used with a 2x Barlow or a .5 focal reducer, and also as a finder scope.

I looked at the listing carefully and decided this was the same scope made for other companies, but at a lower cost. Curiously it has the same model number as a 50mm finder, so I wasn't sure I was going to receive a 60, but I did. I mounted it to my Celestron 8SE to be used as an autoguider as shown in the photo It is actually a bit longer than I expected, but fits the 8SE well after I added a second vixen bar to give it plenty of support. I didn't use the narrow dovetail that came with the scope, however it is well made. so I may reuse that for another purpose. Instead I mounted the rings onto an extra pair of clamps I had. The optical quality is very nice. No visible aberrations or distortions from edge to edge, and the image is nice and bright with crisp contrast. I do see a purplish colored coating on the objective, so it may have an antireflection coating of some kind. I may need to tweak the focuser once I attach the camera, but for just using an eyepiece, everything works well and is smooth without being overly loose or overly tight. The only thing I didn't care for were the six inexpensive screws used to center the scope in the rings. They seem to be cast aluminum and not machined in any way. I may clean them up later with a die cutter. I also will add some lock nuts before my final alignment with the main scope, just to keep everything aligned and tight. So overall, I'm happy with the purchase and I think Svbony needs to be considered when choosing products of this type.

This scope is very well constructed and features a nicely designed fine focus to supplement the coarse focus, thus allowing it to accommodate virtually all 1.25 in. cameras such as the ZWO 120 Mini. At the top of the customer reviews are two by identified as "Just Asking" and another by D. Nasser both of whom apparently have no idea what they're talking about. I too have a ZWO 120 Mini guide camera and it fits absolutely perfectly with the SV106 guide scope. The scope has three ways to focus the camera: a course focus, a wonderfully implemented fine focus, and the ability to move the camera in and out of the mounting tube for a very coarse focus adjustment. With the camera fully seated in the mount and the coarse focus extended about 2/3, the camera achieved absolutely perfect focus with much capability to spare. Note that some other reviewer's have left similar comments, also, noting that the ZWO 120 Mini easily fits with this guide scope. An absolutely great piece of kit! It's too bad that some of the reviewer's apparently don't know how to operate a lens...

Scope is well constructed, currently using as a finderscope, objects are much brighter than the default 30mm finderscope that my telescope came with. Note that the scope as straight thru for eyepiece only, I could not get it to focus with a star diagonal. The scope also gives me flexibility to use it as a guidescope in the future. The focusing system is precise but I found the dual focusing to be a bit tedious and focus locks do not work that well, I could still adjust the focus after tightening down the focusing lock screws.In all, a great scope, great value, good versatility.

this guide scope is worth valie. I used as telescope with pc and i get beatiful video time.

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 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.

This works excellent. I had put this on my etx, 125 telescope.As a finding scope and it works excellent. If you're looking to buy one of these, these are well made goods good. Uh, good glass. The coating on the glass is well done. I have enjoyed this very much
