Byers series 2 Tangent Arm drive Mount and tripodThis massive mount and tripod can hold 130 lbs of payload and move it so accurately that you will not need to guide your ccd camera for up to 2 hours if you have it perfectly polar aligned and have the tangent arm adjusted well.This mount is in excellent condition and works perfectly.
This may be the most accurate mechanical drive ever made for an amateur astronomer. The tangent on the RA can run for 2 hours before needing to be reset. Plenty of time for a deep ccd exposure. The original cost of this mount was $6,500, with inflation about $10K. This is a great deal. You can pick it up for free or I can deliver it for $1 per mile from 86444. This can be transported and set up by one strong person, as the tripod is aluminum, but it really should be put into an observatory.If you want solid unparalleled tracking accuracy for your telescope, this is the mount to buy and you can buy it at a true bargain.An extra motor and hand control is included so you don't have to worry about failures.
