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.

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.

Well put together piece of kit. No instructions, but it seems fairly obvious how to use it.

Love it

I have just received my order and the red dot doesn’t seem to turn on, I’ve turned all the knobs every-which way and it’s Still not turning on, is there something I’m missing? Help

I've purchased several of these (this brand and others) and for the money, you can't beat them. The only significant difference (I notice) between this Brand and a different/more-expensive Brand is the Battery-Cover and I prefer this one. For both this Red-Dot (and my Telrad's) I made a Gizmo to enable my forgetting to turn it Off (the Gizmo will go-to-Sleep and pull only 1uA (yes, Micro-Amp, not Milli-Amp). This is accomplished by using an ATtiny85, Sleep-Mode and my code). These Red-Dot's use a single 2032-coin battery and they typically have 220-mAhr Capacity, thus could forget about turning it Off for many years! (do the math...) I've done them on Mini-BreadBoards and PerfBoards... photo Needed to make a Fake Battery (some cardboard disc's with Foil-wrapped on Wire ends)
