Daystar Quantum Rear Combo plate - SCT/T
The Daystar Quantum Rear Combo Plate (Q3RFCTM) is a specialized adapter designed to integrate your Daystar Quantum filter into a standard imaging train. It provides a critical link between the filter body and your camera or telescope accessories by offering two essential thread types: a female T-thread and a male 2" x 24 SCT thread.
SCT/T-Thread Connectivity for Daystar Quantum Filters
This combo plate solves a common connectivity challenge by providing two distinct mounting options on a single component. The female T-threads (M42x0.75) allow for a direct and secure connection to DSLR T-rings, filter wheels, or other T-threaded imaging accessories, creating a rigid connection for photography.
The male 2" x 24 TPI thread is specifically designed for compatibility with Schmidt-Cassegrain Telescope accessories and dedicated Daystar hardware, including the RF2D2 or GF2SCTT units. This ensures your Quantum filter can be properly integrated into a variety of optical setups. Please note that product photos may show a different model; this Q3RFCTM plate features female T-threads as described.

What is the Daystar Quantum Rear Combo Plate Q3RFCTM used for?
The Daystar Q3RFCTM is a mechanical adapter that screws onto the rear of a Daystar Quantum filter. It provides the necessary threads to connect the filter to either a camera via T-threads or to specific SCT accessories using its male 2" x 24 threads.
What are the specific thread types on the Q3RFCTM plate?
The Daystar Q3RFCTM features a dual-thread "combo" design:
-
Female T-thread: Standard M42x0.75 thread for connecting to most astronomy cameras, T-rings, and filter wheels.
-
Male 2" x 24 TPI thread: For connecting to SCT-specific accessories and Daystar's RF2D2 or GF2SCTT hardware.
How do I use the Daystar Quantum Q3RFCTM plate with my Schmidt-Cassegrain Telescope (SCT)?
For an SCT setup, you would typically use the male 2" x 24 TPI thread on the Q3RFCTM plate. This allows you to connect the Quantum filter to compatible SCT visual backs, focal reducers, or specific Daystar accessories like the GF2SCTT, ensuring a secure fit within your telescope's optical train.
Can I use the Daystar Q3RFCTM to attach a DSLR camera to my Quantum filter?
Yes. The female T-thread on the Q3RFCTM plate is the industry standard for astrophotography. You can attach a brand-specific T-ring to your DSLR camera body, which then screws directly into this plate, creating a solid connection for imaging.
Is the Q3RFCTM plate compatible with all Daystar filters?
This plate is specifically designed for the Daystar Quantum series filters. It may not be compatible with other Daystar product lines like the Quark. Always verify compatibility with your specific filter model before purchasing.
The product photo looks different. What threads will I receive?
You will receive the Q3RFCTM model, which has a female T-thread. The manufacturer has noted that some stock photos may incorrectly show a different plate (model Q3RFC1M) which has a 1.375"x24 thread. This product is confirmed to have the female T-thread for camera connections.
