Worst piece of junk I ever bought. I even felt bad about returning it. When the illumination was advanced enough to see the wires it flooded the field of view making the guide star invisible. The contrast was very very poor also. Save up and buy the Takahashi model. You wont be disappointed in that one. Promise.
No eyerelief 3mm is generous. Grease from the adjustment screws continues to bleed on to the internal lense. No accurate way to return the reticle to center. Too bright and washed out. I feel ripped off and actually think I got a returned item to begin with.
