What is the primary function of the Baader Hyperion DT-Ring SP54/M43?
The Baader Hyperion DT-Ring SP54/M43 is designed for afocal photography (digiscoping). It physically connects a Baader Hyperion eyepiece to a camera lens that has a 43mm (M43) filter thread, creating a secure connection for taking pictures through the eyepiece.
Which eyepieces are compatible with this Baader DT-Ring?
This ring is designed specifically for the Baader Planetarium Hyperion eyepiece series. It attaches to the SP54 thread found on the top of these eyepieces after the original rubber eyeguard has been removed.
What kind of camera can I connect with the M43 thread on this DT-Ring?
The M43 male thread is designed to screw into the front filter thread of a camera lens. You need to ensure your camera's lens has a 43mm filter diameter. This is common on some Micro Four Thirds kit lenses and other compact camera systems. It is not a direct connection to a camera body.
Why is the short design of the Baader Hyperion DT-Ring important?
A short connection is critical to prevent vignetting, which is the darkening of the corners of an image. By minimizing the distance between the eyepiece's last lens and the camera's front lens, the DT-ring ensures the entire camera sensor is illuminated by the light coming from the eyepiece.
How do I attach the SP54/M43 ring to my Baader Hyperion eyepiece?
First, unscrew and remove the rubber eyecup assembly from the top of your Hyperion eyepiece. This will expose the male SP54 threads. You can then screw the female SP54 side of the DT-Ring directly onto these threads until it is snug.
Can I use this Baader DT-Ring to connect my DSLR with a 52mm lens to a Hyperion eyepiece?
No, not directly. This adapter has M43 threads. To connect a lens with a 52mm filter thread, you would need a separate step-down ring (52mm to 43mm), placed between this DT-Ring and your camera lens. However, adding more adapters increases the risk of vignetting.
