Made in Japan, this a 12 mm Kellner design for 1.25" eyepiece holders.
Double crosshair reticle (see simulation).
On/off switch + continuous brightness control. Wattage of LED unknown (see photo) but guessing 0.1 W to 1 W.
Requires two SR-44 button cell batteries, not included, usual positive-side-up installation.
20 years old but excellent condition and fully functional. A few minor scuffs (not scratches).
Older non-integrated design requires cable between LED and controller (included).
Reason for selling: Not doing astrophotography anymore, seen it, been there, done it. Switching to visual observing only.
Will ship USPS First Class Package.
