Meade Electronic Eyepiece with RCA video out cable to send images directly to your TV, VCR, or computer. Includes thread-on barrels for 1.25-inch. Powered by a 9v battery (not included). This small-array monochrome eyepiece will have a field of view similar to a high powered 4mm eyepiece. Gain control is adjustable via a thumb dial. Purchased last December and in perfect condition. Costs $70. Will sell for $50. Price includes shipping at my expense in CONUS. Check or money order accepted. E-mail me if you have any questions. Thanks for looking.
