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

Love it

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)

Awesome product

No particular way to mount

Works like a charm.

Don’t let this fool you in thinking that it’s the same as the celestron red dot. It’s not!!! The brightness level at the dimmest is VERY bright. It does a poor job in preserving your night adapted vision. One of my colleagues have the celestron red dot finder and it works flawlessly and consistently. I clearly can’t rely this for my 80mm APO for visual use. It has a finite amount of play until I can’t adjust any further. In other words, I can’t get it close enough to my field of view and it bottomed out. Did I forget to mention? There’s no battery included so have fun with that!!! Last one is an issue and I worked around its lack of adjustability and said that each object is 4 degree to 7 o-clock on the red dot to get it right. That position is never consistent and I find myself having to bottom it out to get back to the calibrated spec. I don’t recommend this red dot. Kinda wish I never shattered/trashed it out of frustrations so I can return it. Experienced tip: get a Rigel quick finder if you want something that’ll work for a small grab and go. It straps onto the dew shield with a double sided tape to secure the base in place. Then snap on the head in place. It all fits my well-stuffed case!!!
