Hi, I bought a Losmandy Dovetail plate celestron 08 which is listed at Bintel for $ 159 page 5 of telescope accessories and Losmany Guide scope 125mm for $259 as listed. Web site address is
www.bintelshop.com.au/welcome.htm
Make sure you phone and ask if would suit as I had to take some measurements of screw placements so I got the correct attachment device from my C8 tube to the Dovetail plate.
Good luck
Mark
