Whilst I am very pleased with this pier - gives me plenty of clearance and is well made. I did have a bit of a headache is fitting on my Berlebach Planet tripod which has the EQ5 / HEQ5 fitting. Turns out that German tolerances are more accurate than Chinese and the silver EQ5 puck supplied with the ZWO pier wouldn’t fit my tripod. Too big ! I also tried on my Sightron tripod again the EQ5 wouldn’t fit. However the pier using the larger puck does drop straight into the Sightron tripod without a problem. My advice is do some research unless you plan to go with the either the ZWO carbon tripod or a Skywatcher steel EQ5. Alex has been first rate in his help and advice. Thank you
