Baader Hyperion DT-Ring - SP54/M58

First, unthread the rubber eyeguard from your Baader Hyperion eyepiece to expose the SP54 threads. Next, screw the DT-Ring onto these threads until it is snug. Finally, carefully thread your camera lens, which must have a native M58 filter thread, onto the other side of the ring.

This adapter is specifically designed for Baader Planetarium Hyperion eyepieces. These eyepieces feature an SP54 thread beneath their removable eyeguards for direct attachment of accessories like this DT-Ring.

The ring connects to any camera lens that has a standard M58 (58mm) filter thread on the front. If your camera lens has a different filter thread size, you will need an additional step-up or step-down ring to adapt it to M58.

For high-resolution lunar imaging, stability is key. A universal mount that clamps onto the eyepiece can introduce slight flex or tilt, blurring fine details. The Hyperion DT-Ring SP54/M58 creates a solid, threaded connection that eliminates this movement, ensuring your camera remains perfectly parallel to the focal plane for maximum sharpness on features like the Rimae Sirsalis or the central peaks of Copernicus.

Yes, this is an excellent application. When imaging a bright planet like Jupiter, you need a very stable connection to capture fine details like the Great Red Spot or subtle cloud bands. The rigid connection provided by the Hyperion DT-Ring prevents camera shake and ensures perfect optical alignment, which is critical for achieving high-resolution planetary results with an SCT.

The short physical length of the adapter minimizes the distance between the eyepiece and camera lens. This helps prevent vignetting (darkening of the corners of your image) and ensures the brightest, most evenly illuminated field of view your camera can capture.
