Rusan reduction ring for the ARM52 adapter is a special connector necessary to attach the Pulsar Pulsar attachment to the adapter buckle.

Dedicated reduction ring to the Rusan adapter

In the event that we have a cap with thread other than M52 × 0.75, its assembly to the telescope, apart from the Rusan clamp adapter, requires a special reduction ring. Our offer includes Rusan reduction rings for the most popular models of thermal imaging and nighttime attachments. Installation of the ring to the Rusan adapter takes only a few seconds and does not require the use of tools.

The ring is dedicated to selected models of Pulsar nighttracks: F135/F155/FN455
