If you own a 400, 600, 600E, 800, 900, 1200 or Mach1GTO mount and wish to use a Losmandy Polar Alignment Scope that you already own, you will need to use this adapter with your Polar Scope. It was designed to adapt the scope to the AP thread size.
When purchasing a new Losmandy Polar Scope a PASILL4 version can be purchased which already includes this adapter.
Note: The Q8140-A is shown as silver for easy identification. It is anodized black as a finished product.
Please note that we cannot guarantee that the adapter will fit all Losmandy polar scopes from prior years.
