What is the purpose of the PrimaLuceLab Adapter for ESATTO 3" and FSQ85?
This adapter is a specific mechanical part designed to securely connect the PrimaLuceLab ESATTO 3" robotic focuser to the optical tube of a Takahashi FSQ85 telescope, replacing the telescope's original focuser.
Do I need other adapters to connect my camera to the ESATTO 3" on my FSQ85?
Yes, most likely. This adapter connects the focuser to the telescope. To connect your camera and accessories to the focuser, you will need additional adapters, such as the optional M81 to M72 adapter with stop ring for Takahashi accessories or the optional 2" visual back for standard 2" nosepieces. You may also need extension tubes to reach focus.
Is the M81 to M72 adapter with stop ring included with this FSQ85 adapter?
No. The M81 to M72 adapter with stop ring is a separate accessory that threads into the M81 drawtube of the ESATTO 3" focuser. It must be purchased separately to connect M72-threaded Takahashi accessories.
How do I use a 2" diagonal for visual observing with the ESATTO 3" on my FSQ85?
After installing the ESATTO 3" using this adapter, you must purchase the optional 2" visual back for ESATTO 3" (PL3600210). This accessory threads into the M81 port on the focuser's draw tube and provides a standard 2" receptacle with compression rings for your diagonal or other 2" accessories.
Will this PrimaLuceLab adapter work with the ESATTO 2" focuser?
No, this adapter is designed exclusively for the physical dimensions and thread pattern of the ESATTO 3" focuser. It is not compatible with the ESATTO 2" or any other focuser model.
After installing this adapter and the ESATTO 3" on my FSQ85, how do I set camera rotation for the North American Nebula (NGC 7000)?
To achieve precise camera rotation for framing large targets like the North American Nebula (NGC 7000), you will need the optional M81 to M72 adapter with stop ring. This allows you to loosen the stop ring, rotate your entire camera train to the desired angle, and then lock it down securely without losing focus.
