Check which filter and adapter sizes clear the sensor with the QHYCCD M42 All-In-One Adapter Kit, and how much light the corners lose.
Check vignettingThe QHYCCD M42 All-In-One Adapter Kit is a comprehensive solution for achieving precise spacing and solid connections within your astrophotography imaging train. This kit provides the components to connect the QHY183M with the QHYCFW3S filter wheel and QHYOAGS off-axis guider. It eliminates the trial-and-error of sourcing individual adapters by offering a versatile collection designed to meet common back focus requirements.
Achieving the correct distance between your camera sensor and your corrector is the most critical element for sharp, round stars across the entire field. This QHYCCD M42 adapter kit is designed specifically to solve this problem. By providing a selection of common M42 spacers, it allows you to assemble the exact back focus distance your flattener or reducer specifies, ensuring your optical system performs at its best.
Mixing components from different manufacturers can often lead to connection headaches. The QHYCCD M42 All-In-One Adapter Kit simplifies this by providing matched QHYCCD adapters and spacers in one package. They use QHYCCD's 6-screw spacer system, which is more robust than a typical threaded connection.
The primary purpose of the QHYCCD M42 All-In-One Adapter Kit is to provide a versatile set of spacers and connectors to achieve precise back focus and create secure connections between the QHY183M, the QHYCFW3S filter wheel and the QHYOAGS off-axis guider.
Most field flatteners and reducers require a very specific distance to the camera sensor (e.g., 55mm) to function correctly. This kit provides various M42-threaded adapters and spacers that you can combine to precisely match that required distance, ensuring your stars are sharp from edge to edge.
The M42 All-in-One Kit is only suitable for use with the QHY183M and QHYCFW3S. Its spacers fit QHYCCD's 6-screw adapter system and are fixed with the supplied M3 screws, so they are not plain T-thread spacers.
Yes. Flexure is often caused by non-threaded, slip-fit connections (like 1.25" or 2" nosepieces). Between the QHY183M, filter wheel and guider, the kit replaces slip-fit parts with screw-fixed QHYCCD adapters and spacers, which helps keep the imaging train rigid.
This kit provides convenience and flexibility. Calculating the exact combination of adapters needed can be difficult, and imaging trains often change. The QHYCCD All-In-One Kit gives you a toolbox of common adapters, saving you the time and expense of ordering individual parts and waiting for them to arrive when you discover you need a different spacing.
You would use the adapters in the kit to build out the correct spacing. First, you'd find an adapter to connect the filter wheel to the OAG. Then, you would use a combination of spacers from the kit to set the required distance from the OAG's pick-off prism to the main camera sensor, while also ensuring your guide camera can reach focus.
