  • Starlight Instruments 2.0" Adapter for Any 2.0" Opening, for FTF2008BCR Focuser

    The Starlight Instruments 2.0" Adapter provides a simple, direct way to mount your FTF2008BCR Feather Touch focuser into any standard 2.0" compression ring holder. 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.

    Mount Your FTF2008BCR in Any 2.0" Port with a 0.8" Travel Limit

    This 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.

    Crucially, 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.

    • Primary Use Case: To mount the FTF2008BCR focuser into a standard 2.0" visual back or compression ring holder, as you would an eyepiece.
    • Critical Limitation: The design restricts inward drawtube travel to a maximum of 0.8". You must verify your focuser's travel and your telescope's focus point before use.
    • Construction: Machined by Starlight Instruments in the USA to provide a precise, no-slip fit for your Feather Touch focuser.

  • Can I use this adapter with my FTF2008BCR on a Celestron SCT's 2" visual back?

    Yes, this is a primary use case for the Starlight Instruments 2.0" Adapter. It lets you slide the FTF2008BCR into the visual back like an eyepiece. However, you must ensure your imaging train or eyepiece can reach focus within the 0.8" of inward travel allowed by the adapter.

    What is the 0.8" travel limitation on this Starlight Instruments 2.0" Adapter?

    The adapter's internal depth is 0.8 inches. When you rack the FTF2008BCR's drawtube inward, it will physically stop when it hits the bottom of the adapter. This means you can only use a maximum of 0.8" of the focuser's inward travel before it bottoms out.

    Does this adapter fit any focuser other than the Starlight Instruments FTF2008BCR?

    This adapter is specifically designed and dimensioned for the Starlight Instruments FTF2008BCR Feather Touch focuser. It is not guaranteed to fit or provide a secure connection for other focuser models, even if they have a similar body size.

    I want to use my FTF2008BCR for imaging on a refractor. Is this 2.0" adapter the best way to mount it?

    While this adapter will physically connect the focuser, a more rigid and permanent solution like a dedicated flange adapter is generally better for astrophotography. This 2.0" slide-in adapter is best for visual use or when a permanent modification isn't possible, keeping the 0.8" travel limit in mind.

    Why would I use this adapter instead of a dedicated mounting plate for my FTF2008BCR?

    This adapter is for versatility and non-permanent setups. 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. Its main trade-off is the limited 0.8" travel and potentially less rigidity than a bolted-on plate.

    Does this Starlight Instruments adapter thread onto my telescope?

    No, this adapter does not use threads to connect to the telescope. It has a smooth 2.0" barrel that slides into a telescope's 2.0" compression ring or visual back and is secured by the telescope's own thumbscrews, just like an eyepiece or star diagonal.
