Know before you buy
No, this is a manual adapter. It does not provide electronic communication between the lens and the camera, so you will need to focus manually and use lenses that allow for manual aperture adjustment.
This adapter uses a standard M42x0.75 male thread. If your specific ASI camera model uses a different connection, you may need an additional adapter or spacer to achieve the correct mounting.
Yes, the drawer is designed to accommodate standard 2-inch mounted filters with M48x0.75 threading. It is ideal for color or narrowband filters commonly used in astrophotography.
The 29mm back focus is the fixed distance between the camera sensor and the lens mount. You must ensure your specific camera and any additional spacers you are using align with this requirement to achieve proper focus across the entire frame.
Yes, the drawer design allows you to slide the filter in and out without needing to disassemble your imaging train. This makes it convenient to switch between different filters during a single session.
