What is the primary function of the PrimaLuceLab Adapter from M98 to M68 for the ESATTO 3.5" LP?
This adapter's main purpose is to convert the M98 male thread on the draw tube of an ESATTO 3.5" LP focuser to a versatile M68 female thread. This allows you to securely attach a wide range of astrophotography accessories, such as cameras and filter wheels, that use the M68 standard.
How does the stop ring on the M98 to M68 adapter help with astrophotography?
The integrated M68 stop ring allows you to precisely set the rotational angle of your camera. You can thread your camera on, loosen the ring to orient your camera sensor perfectly with your target, and then tighten the ring to lock it in that position. This is essential for achieving optimal framing for your images.
Which focuser is this M98 to M68 adapter designed for?
This adapter is specifically designed for the PrimaLuceLab ESATTO 3.5" LP low-profile robotic focuser. It threads directly onto the M98 draw tube of this model.
I have a full-frame camera with an M68 thread. Can I use this adapter to connect it to my ESATTO 3.5" LP focuser for imaging the Andromeda Galaxy (M31)?
Yes, absolutely. This adapter is the correct component to connect your M68-threaded camera to the ESATTO 3.5" LP. The stop ring will be particularly useful for framing a large target like the Andromeda Galaxy (M31) to fit perfectly on your full-frame sensor.
If I attach a heavy filter wheel and camera to the ESATTO 3.5" LP using this adapter, will the stop ring hold the rotation securely?
Yes, the stop ring is designed to provide a secure lock, maintaining the rotational position even with a heavy imaging train. Once tightened, it prevents unwanted rotation, ensuring your framing remains consistent throughout an imaging session.
Does this adapter change the thread type from the ESATTO 3.5" LP focuser?
Yes, that is its function. It adapts the focuser's native M98 male thread and presents a standard M68 female thread on the camera side, expanding the range of compatible accessories.
