Daystar Quantum Front Flat Plate - 1.375"x24TPI (F)
The Daystar Quantum Front Flat Plate enables custom integration of your Quantum series solar filter into a specialized optical train. This plate replaces the filter's standard front plate, providing a secure, female 1.375"x24TPI threaded connection for direct attachment to compatible hardware.
Custom Mounting with 1.375"x24TPI Threads
This front plate is the solution for imagers and observers building a non-standard solar setup. The 1.375"x24TPI female thread is a specific size that allows you to directly couple the Quantum filter to custom adapters, camera lenses, or other specific optical components, bypassing the need for generic step-rings. This ensures a rigid, perfectly aligned connection critical for high-resolution solar imaging.

What is the Daystar Quantum 1.375"x24TPI Front Flat Plate used for?
This plate is a specialized adapter that allows you to mount a Daystar Quantum series solar filter onto a telescope or accessory that has a male 1.375"x24TPI thread. It is used to create a custom, secure, and direct-threaded connection in your optical setup.
Which Daystar filters are compatible with this Front Flat Plate?
This plate is designed specifically for the Daystar Quantum series of H-alpha filters. It is not intended for use with Daystar Quark or other filter models.
Why would I need to replace the original plate on my Daystar Quantum filter?
You would replace the original front plate if you need to mount the filter to an optical system that doesn't match the stock adapter. This plate provides a specific 1.375"x24TPI thread, which might be required for a custom imaging train, a specific telephoto lens adapter, or a particular telescope's focuser or visual back.
How do I install this Daystar Quantum Front Flat Plate?
Installation involves carefully unscrewing the existing front plate from your Daystar Quantum filter body and then threading this new plate in its place. Ensure the threads are clean and engage smoothly to avoid cross-threading. The process should be done in a clean, dust-free environment.
Is the thread on this Daystar plate male or female?
The Daystar Quantum Front Flat Plate has female (internal) 1.375"x24TPI threads. It is designed to screw onto a corresponding male thread.
Can I use this plate to attach my Quantum filter to a standard 2" focuser?
Not directly. A standard 2" focuser does not have 1.375"x24TPI threads. To use this plate with a 2" focuser, you would need an additional adapter that steps down from the focuser's native thread (often M48 or SCT thread) to the male 1.375"x24TPI thread this plate requires.
