Baader Planetarium's 14mm Finetune ring increases the magnification of Hyperion eyepieces. Simply screw this finetune ring in between the eyepiece body and negative lens assembly for an instant power boost.
Combine a 14mm and 28mm finetune ring for even more magnification.
For astronomers looking for the Hyperion 3.5mm eyepiece (now discontinued), using this finetune ring with the Hyperion 5mm yields 4mm with a better image than the 3.5mm could provide.
