What is the purpose of the PrimaLuceLab Adapter for the ESATTO 3" and Takahashi TSA-120?
This adapter serves as the mechanical interface to securely mount a PrimaLuceLab ESATTO 3" robotic focuser onto a Takahashi TSA-120 refractor. It allows you to upgrade your telescope with a robust, remotely-controlled focusing system for astrophotography.
I have a Takahashi TSA-120 and want to automate my focusing. Is this the only part I need?
No. This adapter is only one component of a complete system. You will also need the PrimaLuceLab ESATTO 3" robotic focuser itself, along with any necessary camera adapters or extension tubes to connect your specific imaging train and reach focus.
Can I use my existing Takahashi accessories with the ESATTO 3" focuser using this adapter?
Yes, but you will need the appropriate optional adapters from PrimaLuceLab. By adding camera adapters with a stop ring, you can connect your existing Takahashi accessories to the ESATTO 3" focuser's draw tube.
If I'm imaging a faint target like the Veil Nebula (NGC 6960) with my TSA-120, how does this adapter help?
This adapter enables the use of the ESATTO 3" focuser, which provides extremely fine, repeatable focus adjustments. For a detailed, low-contrast target like the Veil Nebula, achieving critical focus is paramount for resolving fine filaments. This system allows you to make those adjustments remotely and precisely, which is crucial during a long imaging session.
Can I use the ESATTO 3" focuser for visual observation on my TSA-120 with this adapter?
Yes. To use the ESATTO 3" for visual astronomy, you will need to add the optional 2" visual back for ESATTO 3". This accessory threads onto the focuser's draw tube and allows you to insert standard 2" diagonals and eyepieces.
I want to rotate my camera for better framing on a target like the Andromeda Galaxy (M31). Does this system allow for that?
Yes, camera rotation is possible with the right accessories. You would need an optional camera adapter for the ESATTO 3" that includes a stop ring. This feature allows you to lock your camera at any desired angle, making it easy to compose wide-field targets like the Andromeda Galaxy (M31).
