Great 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.

SV Eyepiece Illuminator model EI002
This item is all machined aluminum and well made. It looks nice. My only issue is that it appears that the battery is not user replaceable. No instructions came with this item. I could not unscrew the knurled part as it was extremely tight.
Mark: Thank you for your input. I have placed instructions on the web page showing how and where to open the illuminator to replace the batteries. Thanks again for your comments.

EI002 Illuminator
Illuminates crosshairs evenly. Does what it’s supposed to.

Finder scope illuminator
Excellent product, good price and fast shipping. These days, fast shipping is hard to come by so I was pleasantly surprised when it showed up so quickly. Thanks Stellarvue!

Illuminator
I had a Meade 9mm double cross bull-eyed eyepiece that the illuminator quit working. I purchased this one and it fit perfectly into my existing eyepiece! It even came with the batteries, you can't go wrong with purchasing this.

Does exactly what it’s supposed to…perfect brightness
Good construction and the switch doesn’t feel cheap. Brightness level is perfect. Threads smoothly and easily into the finder eyepiece.

Reticle illuminator
Good value and it's very light

Does what it should, with some flaws
Two issues I've found:
1. The minimum brightness is a bit bright when trying to aim at faint stuff. It just needs to be barely brighter than the sky background, and at a light polluted site it would be ok, but at a dark site (where you need it most), it's a bit too bright. I took a sharpie to the LED to dim it a bit and that helped.
2. It's too heavy and acts as lever against the focusing mechanism of the finder. In warm weather, the grease in the helical focuser of a Stellarvue finder is quite viscous and depending on the telescope's orientation, the weight of the illuminator actually causes it to rotate. A counter-weight on the other side of the focuser is needed.
