Adapter M54 to M48

The adaptor has two functions:

• Short adaptor to M48 for filter wheels with M54 thread connection: Many filter wheels have an M54 internal thread connection. This adaptor reduces the thread to M48 and allows for flexible further adaptation. The optically effective length of the adaptor is only 1.8 mm.
• Adapter for 2" filters on camera lenses for astrophotography: The adapter allows you to adapt 2" filters to various camera lenses. The adapter has a continuous M48 filter thread. This means that 2" filters and adapters with a very short connection thread are sufficient, and very good adaptation is still possible.
