This time I have an adapter for 5.5" ID pier tube. The black anodized base is the actual base of a Losmandy GM-8. Therefore, this base will fit a Losmandy tripod or any other pier/tripod with a 5.5" I.D. The 8" x 3/8" aluminum disc is mounted to the GM-8 base with the 2 shown allen bolts to provide further mounting options. Namely, the 3 each x 3.25" radius bolt pattern of a Celestron mount. Don't know if that is the same as Meade. Not shown, but I am including the 3 each 3/8" allen screws for a Celestron mount.
This was my solution to mounting the larger than 6" diameter Celestron bolt pattern to a 5.5" ID pier tube.
The GM-8 base alone cost my $75. Asking $60 for the complete assembly, shipped CONUS. money order or Paypal, please.
Thanks for looking.
