What is the primary purpose of the PrimaLuceLab M110 to M95 adapter for the ESATTO 4"?
Its sole purpose is to convert the M110x1 male thread on the draw tube of an ESATTO 4" focuser into an M95x1 female thread. This allows you to attach camera adapters and accessories from Takahashi, which commonly use the M95x1 thread standard.
Will this adapter work with the PrimaLuceLab ESATTO 2" or 3" models?
No. This adapter is designed exclusively for the ESATTO 4" focuser, which uses a large M110x1 draw tube thread. The smaller ESATTO models use different thread sizes and are not compatible.
Is this adapter required to use a Takahashi FSQ-106 with an ESATTO 4" focuser?
Yes, if you intend to use Takahashi's own photographic adapters behind the focuser. The PrimaLuceLab ESATTO 4" provides the focusing mechanism, but this adapter provides the correct M95x1 threading to connect to the rest of the Takahashi-specific imaging train.
How does the ESATTO 4" with this adapter improve imaging on a Takahashi telescope?
While Takahashi focusers are excellent, the ESATTO 4" offers robotic, temperature-compensated focusing with high payload capacity. This adapter lets you combine the optical excellence of a Takahashi scope with the advanced, automated focusing control of the PrimaLuceLab ecosystem, which is critical for maintaining sharp focus over long imaging sessions as temperatures change.
Is this a slip-fit or threaded connection to the ESATTO 4" focuser?
This is a fully threaded connection. It screws directly onto the M110x1 thread of the ESATTO 4" draw tube, ensuring a rigid, flex-free attachment for your imaging equipment.
Do I need this M110 to M95 adapter if I'm not using Takahashi accessories?
Most likely not. This adapter is specifically for connecting accessories that require an M95x1 female thread, which is most common in the Takahashi ecosystem. If your camera or reducer uses a different thread, PrimaLuceLab offers other adapters for the ESATTO 4".
