  • Baader Hyperion Finetuning-Ring - 14mm M48/M48

    The Baader Hyperion 14mm Finetuning-Ring threads directly between the main body and the front lens assembly of a Hyperion eyepiece, using its M48 threads to precisely increase magnification. This 14mm extension alters the eyepiece's focal length without adding new optical elements, preserving the original design's image quality while giving you more power from a single eyepiece.

    Modify Hyperion Eyepiece Focal Length with the 14mm Finetuning Ring

    The Baader Hyperion eyepiece system is modular, allowing you to change its effective focal length by adding Finetuning Rings. This 14mm ring threads via its M48 connections between the main eyepiece body and the front negative lens group. By increasing the spacing between lens groups, the ring reduces the eyepiece's overall focal length, providing a significant boost in magnification.

    • Maintain Optical Quality: Because you are only adding a precision-machined spacer, not glass, the high-contrast, sharp-to-the-edge view of the Hyperion eyepiece is preserved.
    • Cost-Effective Magnification: Instead of buying a completely new eyepiece, this single ring gives you another focal length option from your existing Hyperion collection.
    • Secure M48 Threads: The M48 filter threading provides a secure, non-flexing connection that maintains perfect optical alignment between the lens groups.

    14mm vs. 28mm Finetuning Rings: Choosing Your Magnification Step

    Baader offers two primary Finetuning Rings for the Hyperion series: this 14mm version and a longer 28mm version. The choice depends on how large a magnification jump you need for your observing targets. The rings can also be stacked to achieve a maximum effect.

    • 14mm Ring: Provides a moderate increase in magnification, ideal for splitting tight double stars or resolving more detail on planetary disks when seeing conditions are good.
    • 28mm Ring: Offers a more substantial jump in power, useful for examining small planetary nebulae or when you need the highest possible magnification your telescope can support.
    • Stacked (42mm): Combining the 14mm and 28mm rings produces the largest magnification increase, a configuration best reserved for nights of excellent atmospheric stability.

  • How do I install the Baader Hyperion 14mm Finetuning Ring?

    Installation is straightforward. First, unscrew the front barrel assembly (the section containing the 1.25" chrome barrel) from the main body of your Hyperion eyepiece. Thread the 14mm Finetuning Ring onto the main body's exposed M48 threads, then re-attach the front barrel assembly to the other side of the ring.

    Which Baader eyepieces are compatible with the 14mm Finetuning Ring?

    The Baader Hyperion 14mm Finetuning Ring is designed for the Baader Hyperion modular eyepieces (such as the 5mm, 8mm, 10mm, 13mm, 17mm, 21mm, and 24mm models) and the Hyperion Aspheric eyepieces. It is not compatible with the Hyperion Zoom eyepiece.

    How will the 14mm Finetuning Ring affect views of Jupiter through my 13mm Hyperion eyepiece?

    Adding the Baader Hyperion 14mm Finetuning Ring to a 13mm Hyperion eyepiece significantly reduces its focal length, thereby increasing magnification. This higher power makes it easier to resolve fine details like the individual cloud bands, the Great Red Spot, and transits of Jupiter's Galilean moons. It effectively turns your mid-power eyepiece into a dedicated planetary eyepiece.

    Can I stack the Baader Hyperion 14mm Finetuning Ring with the 28mm ring?

    Yes, the rings are designed to be stackable. You can thread the 14mm and 28mm rings together for a total extension of 42mm. This will produce the highest possible magnification from your Hyperion eyepiece, though it will also cause the most significant reduction in eye relief.

    Will using the Baader Hyperion 14mm Finetuning Ring affect eye relief?

    Yes, as a general rule, reducing an eyepiece's focal length by adding extension rings will also reduce its eye relief. The effect is moderate with the 14mm ring but becomes more noticeable with longer extensions. Observers who do not require glasses may find it perfectly comfortable, but it is an important trade-off to be aware of.

    Is the Baader Hyperion 14mm Finetuning Ring useful for viewing large objects like the Andromeda Galaxy (M31)?

    No, this accessory is designed to increase magnification and narrow the field of view for smaller targets. To view large objects like the Andromeda Galaxy (M31), you need low magnification to fit the entire object in the field. For that, you would use a long focal length eyepiece like the 24mm Hyperion with no Finetuning Rings attached.
