I would look for a quality illuminated recticle scope like Leo / Burris / Bush 4200 / etc., and for reliabilities sake, stay away from the cheap stuff, especially when illumination is involved. Make sure it has vairiable brightness controls. Something in the 3x9 or so range is fine. I have a Burris Fullfield ll in 3x9 with the Illuminated B Plex recticle, and it works fine at night, without over powering the target and spoiling your night vision. Another tactic we use hunting dogs at night up in Maine in the winter is a million CP portable spotlight with a red lens cover. I am not sure why, but they seem to be able to see the red light, but it does not spook them right off the bat. It gives you time to take the shot.
