What is the primary function of the Adapter Kit - Combo E1?
The primary function of the Adapter Kit - Combo E1 is to set the correct 55mm back focus distance between a compatible QHY camera (like the QHY533C or QHY294C) and an M48 threaded accessory, such as a coma corrector or field flattener. This precise spacing is critical for achieving sharp, aberration-free stars across the entire field of view.
Which QHY cameras does the Combo E1 Adapter Kit support?
The Combo E1 Adapter Kit is specifically designed for the following QHY color cameras: QHY533C, QHY294C, QHY163C, and QHY183C. It can also be used with the monochrome versions of these cameras if you are not using a filter wheel.
How do I use the Adapter Kit - Combo E1 to connect my QHY533C to a coma corrector with M48 threads?
You will select the appropriate combination of the three included adapters to bridge the gap between the QHY533C's sensor and the 55mm requirement of your M48 coma corrector. The specific combination depends on your camera's native back focus. The included 0.5mm spacer can be added or removed for fine-tuning to achieve perfect correction.
I want to use my QHY163M with an f/4 Newtonian's coma corrector, but without a filter wheel. Is the Combo E1 kit right for this?
Yes, the Adapter Kit - Combo E1 is perfectly suited for this scenario. Since you are not using a filter wheel, which would consume a significant amount of back focus, this kit will provide the correct spacing to connect your QHY163M directly to the coma corrector and achieve the required 55mm distance for optimal performance in your f/4 Newtonian.
Does the Adapter Kit - Combo E1 include the adapter for a Canon or Nikon DSLR lens?
No. While the Combo E1 kit can be part of a solution for attaching DSLR lenses, it does not include the main lens mount adapter. You will need to purchase a separate M48 to Canon EF or M48 to Nikon F adapter to complete the connection.
What is the purpose of the 0.5mm spacer in the Combo E1 kit?
The 0.5mm spacer is included for fine-tuning the back focus distance. While the main adapters get you very close to the target 55mm, slight variations in manufacturing tolerances of other components can affect the final spacing. The 0.5mm spacer allows you to make precise micro-adjustments to achieve the sharpest possible stars.
