EI002 Illuminator

Light weight, aesthetic appearance, smooth turn anc click on/off dial, and clear well defined crosshairs.

This crosshair reticle illuminator seamlessly replaced an older and less well-designed unit in an SV illuminated finder eyepiece. The crosshairs are illuminated well, and the illumination is fully adjustable by the micrometer-style rheostat. I have only two suggestions for improvement. First, like all other illuminators I have seen, this one uses watch-style batteries, which are expensive and whose particular size might be challenging to find at the local drug store. A single AAA-driven unit would be better. Second, a black hash mark in the switch and main body, aligned when the unit is "off," would be appreciated. I will be adding such to mine shortly. However, this is a fine illuminator unit--4 stars.

I recently purchased the illuminator to pair up with a Stellarvue 10x60 RACI finderscope. The illuminator has a great, precise feel to the rheostat with fine control of the output illumination. It does a great job of illuminating the crosshairs without overpowering the view. Well done!

I bought one of these several years ago along with a Stellarvue reticle eyepiece. As you would expect from Stellarvue, the combination worked flawlessly. As an active lunar and planetary imager, I gradually accumulated additional reticle eyepieces with illuminators of highly variable quality. I recently purchased two more of the Stellarvue illuminators so that these eyepieces could be used when needed with no surprise outages.

Very pleased.

Limited use so far but vastly superior to prior model. Seems sturdy and variable controls work well. Maybe a 5* with more use.

Mechanically very sound. Perfect fit for my Stellarvue Finder. Smooth brightness control and not too bright. Works beautifully.

I adapted this to an old corded UO Orthoscopic illuminated reticle, and made it cordless. Great product. It has a good rheostat and looks to be built well.

I was in need of a better LED illuminator for my crosshair eyepieces, and I came across the Stellarvue offering. Well, I own several Stellarvue telescopes, so I knew they sold quality gear. These are no exception. Extremely well made, milled to fine tolerances, and the LED has a wide range of illumination, from barely visible to "Holy Crap, That's Bright". I could not be more pleased with this purchase, and I will probably buy a few more to replace my other illuminators. The large knob is not intrusive for my uses, and it have a very solid click detent to the Off position. I highly recommend this illuminator. If you need one, get this one.
