Arrived on time and works great an absolute must for night time use and even some daylight usage.
This is an Awesome Illuminator Looks great and works perfect.
Arrived sooner than promised. It appears to be a sturdier version than what I have been previously using. It has more battery power. I have not tried it out yet. I am hoping to use it to improve my polar axis alignment but it will have use with the star alignment process for my mount. I am pleased.
Very good product at a low price. I liked it so well I bought another one. Very bright but can be turned way down also. Love it.
Fantastic product at a amazing price. I had a hard time making out the recticle on my finder scope. This makes it very easy to see and use.
I picked this up to replace the failed illuminator I received with the Chinese made Orion 12.5mm cross hair EP years ago. I was hoping the threads would be an exact match, but I can only screw the light in about 2 threads. But that turned out to be enough. It works well and I'm very happy with it. Because of the slight thread mismatch I gave it four stars, but I would buy it again.
Works exactly as advertised to make crosshairs visible in the finder even if the sky is very dark.
Works great. Not a perfect fit with my celestron EP but it fits well enough and works better than the other manufacturer's illuminator
I modified this illuminator to work on my old celestron sct finder. It worked great just by popping out the old bulb in the housing and attaching this new illuminator to the old housing. This new unit is very solidly made.
