Tydeux Red Dot Finderscope - Star Pointer Viewfinder Astronomical Telescope Accessories with Slide-in Bracket

No issues. Worked flawlessly out of the box unlike the celestron one.

Very reasonably priced and seems to work well. The adjusting screws work smoothly. It does not come with a battery, and it requires removal of the scope from its base to remove the screw securing the battery compartment. This is a fairly trivial task, and it is supposedly to prevent children from getting access to the battery and swallowing it. The small extra hassle is well worth it if it prevents an injury.

Does what I need, but is quite cheap. Picked this up as I needed a small, light, spotting scope for my astrophotography rig. When adjusting the alignment while it was on my scope, almost broke the adjustment screws, because they barely had enough range to get lined up with where my scope is pointing. So i was just baaarely able to get this to work.
