Ernitec Japan 6-36mm CCTV ULTRAFAST F0.95 meteor astronomy motorized autoiris lens Description: This lens is a high end CCTV lens super to use in astronomy and low light conditions. You appply 12v (or less) at yellow/red cables and you move zoom (reverse polarity to go the other way), and black/green for focus. Iris is AI type ("on lens" videoiris), and it works nice. I can remove it for you (including the light detector window) FOR FREE if you plan to use non-auto iris camera (not complicated, about 30' work). Let me know before shipping, please. Issues: usage marks in body, but lenses are like new. You can check my own telescope set up in www.marronyazul.es. Technical information for astronomy/meteor work: this lens is designed for 1/3" BUT IT WORKS with MINIMAL vignetting in 1/2" sensors (none at max and min zoom, VERY little in the middle zoom range). I tested it on Sony ICX039 old sensor., so it could very well be all you need for meteor work with 1/2" and smaller sensors.
