This adapter is designed specifically for the FTF2008BCR and imposes a critical 0.8\" limit on inward drawtube travel to prevent the focuser from bottoming out inside the diagonal or visual back.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-bg-light\"\u003e\n\u003cdiv class=\"DAV-section\"\u003e\n\u003ch3\u003eMount Your FTF2008BCR in Any 2.0\" Port with a 0.8\" Travel Limit\u003c\/h3\u003e\n\u003cp\u003eThis adapter allows you to install a Starlight Instruments FTF2008BCR focuser onto any telescope that has a standard 2.0\" accessory port, such as a stock focuser's visual back or a star diagonal. The result is a secure, non-permanent mounting solution for adding Feather Touch precision to an instrument that may not have a compatible flange or mounting base.\u003c\/p\u003e\n\u003cp\u003eCrucially, this adapter is designed for focusers with 0.8 inches of drawtube travel or less. If your FTF2008BCR has a longer drawtube, you will be unable to rack the focuser fully inward, as it will physically stop against the inside of the adapter. This makes it ideal for specific visual applications where minimal in-focus travel is required.\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Use Case:\u003c\/strong\u003e To mount the FTF2008BCR focuser into a standard 2.0\" visual back or compression ring holder, as you would an eyepiece.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCritical Limitation:\u003c\/strong\u003e The design restricts inward drawtube travel to a maximum of 0.8\".

It lets you slide the FTF2008BCR into the visual back like an eyepiece.

It's useful for moving your FTF2008BCR between multiple telescopes or for using it on a scope where you don't want to drill new holes for a mounting plate.
