AstromaniaRed Dot Finderscope for Telescope Deluxe Finder, StarPointer Red Dot Sight Metal Reflex Finder Scope for Astronomical Telescope - Red Dot Viewfinder Finderscope with Dovetail Finder Bracket

Bought this to add to my telescope accessories, works well and is a reasonable price. Easy to install and align.

Very solid all-metal construction. I calibrated the alignment in the morning and when I went to test it that night in Jupiter it was spot on. No drift or alignment issues for me. My only qualms are that the color/brightness knob is very hard to turn. Also, a bit of quality control lacking in the reticule shape selector switch; when switched all the way to the right side the reticule projection actually gets displaced significantly. Be advised this does NOT include the required 2032 battery. The dovetail mount did not fit my Koolpte telescope but that's more an issue with my telescope than the finder and was resolved with some metal filing.

Great build quality at fair price.I like Astromania products at a reasonable price and good quality.

Peice of junk. I never take it off the scope and it loses its zero everytime I go to use it. It doesn't matter how much I tighten everything either.

Gives me the options of green or red which is nice as well as the brightness level changes and the dot vs cross hair

I was looking for a better finder scope for my reflector telescope. This scope offers a laser in red or green and several styles of dots, crosshairs and targets.Takes one disc battery - not suppliedWorks great and is easy to align with the telescope with supplied Allen wrench

The two colors are useful, but the 5 brightness settings are the real selling point. If you're looking at something bright, like a Jupiter, you can crank up the brightness to help you distinguish your target. If you want to aim at something dimmer, like the nebula in Orion, then you can notch the brightness down so it's comfortable to view.If you want to zero-in and range your scope in the day time, against a far-off light pole or street lamp, you can change to the green color and the sight works just as well.I use this for my telescope, but the reflex sight itself (without the stand) is compatible with a Picatinny rail. Which is surprising, but not totally unwelcome.

This scope works very well on my Celestron 4SE. The scope is easily Adjusted to calibrate with scope and holds it's adjustment. I wish it had a separate on/off switch. The dial switch is easily left on and it would be nice to not have to leave the preferred brightness to power off. Still, very special. The first red (r green) dot finder scope I have been able to adjust and have it hold its calibration.
