EI002 Illuminator

Great addition to the stellarvue finderscope. Threads into the eyepiece base of the finderscope, illuminating the reticle with an adjustable red light.

The illuminator itself works great -- the brightness of the crosshairs can be gradually increased/reduced from nothing to way-too-bright, and it really makes centering objects in the finderscope very easy. But on just the second use, the on/off switch sort of let go, and just started rotating 360 degrees; it's as though it lost the detent that stops it at "off" or "fully on". However, on subsequent uses it seems to have restored its functionality, so we will see if it will last, especially if I can be careful with it. So, were it not for the switch issue, I would give the unit a 5-star rating, but given that I cannot vouch for its durability, I opt for 3 stars.

REVIEW: Basic Illuminator. To eyepiece M8-1.25. LED diode can be switched out if needed. Attenuation switch came loose at thread and solder joint at negative battery post was broke. Had to re-solder joint and functionality was restored. Fine product, poor assembly. REPLY: I am so sorry you had an issue. For future reference, we would have gladly replaced the defective unit for you. We check these here but it sounds like yours was improperly soldered. Glad you got it working okay. In the future if you get any Stellarvue product that is not 100% call or email us. Thanks for choosing Stellarvue. Vic Maris President Stellarvue

Something's wrong when the illuminator on a $80 -$110 eyepiece dies prematurely. Yet half of mine are dead! What a nice piece for a unassailable price. This is value that I appreciate very much.

Competes the correct image 9X50.

Unit works well. light brightness is easily controlled via control knob.

Bought this illuminator along with the Stellarvue 9x50. Never used an illuminator before and just like other comments here, it makes it a breeze centering objects. The feel and operation of this illuminator is first class. Job well done!

I bought this illuminator to replace a broken plastic illuminator. This illuminator is built of metal and is solid. It fit into my existing eyepiece and works better than the broken one. This one won't break. Excellent product!

I bought this illuminator along with a Stellarvue 9x50 RACI finder scope, to replace a straight through finder scope of another brand. This illuminator is superior to the ones on both my previous finder, and the polar scope on my mount. It has a solid, quality feel. The on-off function has a definite tactile "click" (where my others are a little mushy and tentative). The brightness adjustment is smooth and gives a range of brightness from "just barely there" to brighter than I can ever imagine using. I'll eventually order another of these to replace the illuminator on my polar finder.
