What is the primary function of the PrimaLuceLab M98 to M54 adapter for the ESATTO 3.5" LP?
This adapter's main purpose is to connect any camera, filter wheel, or other astrophotography accessory that has a standard M54 female thread to the M98 male thread on the draw tube of an ESATTO 3.5" LP robotic focuser.
How does the stop ring on the M98 to M54 adapter improve astrophotography?
The M54 stop ring allows you to control the final rotational angle of your camera. This is critical for proper framing of celestial objects, such as aligning your camera sensor with the long axis of a galaxy. You can set the angle precisely without it changing as you tighten the adapter, ensuring perfect composition.
How much back focus does the PrimaLuceLab M98 to M54 adapter use?
The adapter has an optical thickness of just 5mm. This minimal length helps preserve the available back focus in your imaging train, leaving more room for other essential accessories like off-axis guiders and filter wheels.
Can I use this PrimaLuceLab M98 to M54 adapter to orient my camera for framing the Andromeda Galaxy (M31)?
Yes, absolutely. This is exactly what the stop ring is designed for. After threading the adapter onto your ESATTO 3.5" LP, you can rotate your attached camera to align its sensor with the elongated shape of the Andromeda Galaxy (M31) and then lock it in that position using the stop ring for optimal framing.
I have a filter wheel with an M54 female thread. Will this adapter connect it to my ESATTO 3.5" LP focuser?
Yes. This adapter is designed specifically for this purpose. It will thread directly into the M98 draw tube of your ESATTO 3.5" LP and provide a secure M54 male thread to connect your filter wheel.
How do I install the PrimaLuceLab M98 to M54 adapter on my ESATTO 3.5" LP?
Installation is straightforward. You simply thread the M98 side of the adapter directly onto the draw tube of the ESATTO 3.5" LP focuser until it is snug. Then, you can attach your M54-threaded accessory to the other side of the adapter.
